Please let us know if there is anything else we can help with.

Q: Dear Ron.. good morning.. I just got a call from the building; the door closers that we put on 2 weeks ago are leaking oil. We must get there immediately to remedy situation. In our experience, the only way this could happen would be if the screws in the closer were 'backed out'... Do you have any other opinion on how this could happen? They have been performing quite well and we were just at the building on Tuesday and there was no problem with them.. Please give me your opinion.. thank you.. Anne Marie
A: If the bodies are leaking oil the possible causes would be vandalism / abuse type conditions, indeed yes backing out the valves too far is a very common cause, or both are defective but this is unlikely because they brand new units, both failed at the same time and I have personally not had a failure of these bodies since a job in 2011. In my experience - anything is possible.

The facts are this. We can right now and immediately ship 2 - new bodies. To get a credit on these new bodies you will need to send back the initial units for review and inspection. The factory will positively identify the cause of failure with a credit being provided once manufacturer defect is determined. The factory will inspect the rack and pinion, seals (detecting a rupture in the O ring or detecting a specific seal pattern). The detection of your theory will be very easy as the fluid will be absent and the condition of the rack and pinion, seals and O rings will be a near factory condition.

They will also ask for the door size, weight and approx. amount of cycles these are used on a weekly basis. If I recall correctly, these are hold open units. What degree of hold open are the closers templated to. Photos of everything are welcomed and encouraged.

What specifically can I do at this moment to help alleviate the job-site conditions?

Q: Where is the date of manufacture on a 4041 closer?
A: The date stamp on a 4041/4040XP is on the packing nut. The date will be the week of the year and then the year.
EXAMPLE: 10 05 would be week 10 of 2005.
Q: What is the maximum door weight recommended for LCN closers?
A: The maximum recommended door weight for LCN closers is 225 lbs.
Q: What LCN Closers meet the ADA opening force requirements?
A: Any LCN Closer that ends in the number 1, will meet ADA 5 lbs opening forces.
Q: When did LCN quit making traditional potbelly style closers?
A: The LCN "Traditional" series closer line was discontinued in 1980.
Q: How do I get a Size 1 (ADA) closer to close against air pressure?
A: If an Size 1 (ADA) closer is set to 5 lbs. opening force, it will only have about 3 lbs. (60/70%) closing force. If the closer will not close against air pressure, but the ADA requirements have to be met, they may have to change to an automatic operator with a "power boost" option (Senior Swing) if there is that much pressure. If ADA does not have to be met you can increase the spring power on the end of the closer.
Q: What size Allen wrench is used for Closer adjustment?
A: LCN does not supply Allen wrenches, the size that LCN uses, are standard sizes that every installer will have in their tool kit.
  • 3/32" Allen wrench for adjusting regulation valves: main speed, latch, and backcheck
  • 5/32" Allen wrench for adjusting spring power.
Q: What can be done for a door that will not close against wind pressure?
A: To correctly answer this question, we need to know how much more force is required to get the door closed. They could try turning the Rod & Shoe over (short side of shoe towards the hinge), or they may have to go to a sized closer (4016, 4026, 4116) instead of an adjustable closer. They could also try adding a 2nd closer on the door (one on each side of the door). This, however, will make the door harder to open. The answer to this application will be different for each installation.
Q: Does LCN have CAD drawings?
A: LCN CAD detailed drawings are internal confidential documents, and are not available.
Q: What size machine screws are used with thru bolts and a 2-3/4" thick door and a 4040 closer?
A: A 4040 closer mounted with thru bolts on a 2-3/4" thick door would require 1/4-20 X 3-1/2" machine screws.
Q: How do you adjust a door closer and what are the steps to adjust a door closer?
A: All LCN and FALCON door closers will have 3 regulating valves and a spring adjustment. All closers with a "Delay" feature will have an additional 4th valve. For specific instructions on your closer see Installation Instructions here.

Make adjustments below as required.

  • Back Check Valve, (valve #1 as specified in instructions) controls the back check intensity (3/32 allen wrench). Back check is used to slow the door down if someone throws the door open, or if the wind were to catch the door, and blow it open. Back check is used to slow the door down, not to stop the door. If you have a windy environment, or abusive people, (prisons, schools, colleges etc.) you may want to set the back check a little stiffer than you would on a retirement home, hospital doors, day care, etc. Turning the valve clockwise will give you a stiffer back check. Turning the valve counter clockwise will give you a lighter backcheck. If the door must be stopped at a certain position, then a Cush arm can be used, or for more abusive applications, an overhead stop can be used.

  • Main Speed Valve, (valve #2 as specified in instructions) controls the main closing speed of the door (3/32 allen wrench). The main speed is the area from the door in the wide open position down to the last 15°, or so, before the latch. Turning the valve clockwise will make the door close slower. Turning the valve counter clockwise will cause the door to close faster.

  • Latch Speed Valve, (valve #3 as specified in instructions) controls the latch speed of the door (3/32 allen wrench). The latch speed is the last 15°, or so, of closing. Turning the valve clockwise will cause the door to latch slower, and more gently. Turning the valve counter clockwise will cause the door to latch faster, and more abruptly.

  • Delayed Action Valve, controls delay time, on closers so equipped (3/32 allen wrench or flat blade screw driver - depending on closer series and age). For closers installed to 90° template-- when the door is opened past approximately 70°, the closer will delay closing until it comes back to around 70°. Turning the valve clockwise will cause the closer to delay longer (up to approximately 50 seconds). Turning the valve counterclockwise will cause the closer to delay for a shorter time (down to no delay). Please note that the position that the delay will kick in is dependent upon what degree of opening the closer is installed too. For example, closer installed to 180° template, delayed action will kick in only after the door is opened past approximately 95° and is available from approximately 120° to 90° position compared to if the closer was installed to 90° template then it would kick in when the is opened past approximately 70° and be available from 90° back down to approximately 70°. Also, the Closer Spring Force can affect how much delay time can be achieved. The weaker the closer spring force the more delay you can achieve, where as the stronger the closer spring force the less delay time you will have. Closers set to a 5 or 6 spring size will have minimal to no delay time because of the stronger closing force. NOTE: During Delayed Action cycle, the door does not stay in one set spot for the delay time, it will still be in motion during the delay zone based on the delay setting.

  • Spring Adjustment, is located on the end of the spring tube (5/32 allen wrench). It is used to adjust the spring strength (force to close the door). Clockwise gives the closer more closing power (which also makes the door harder to open), and turning the screw counter clockwise, will give the door less closing strength (and makes the door easier to open).
Q: What LCN Closers meet the ADA opening force requirements?
A: Any LCN Closer that ends in the number 1, will meet ADA 5 lbs opening forces.
Q: What does "FP" stand for on an LCN closer?
A: At one time LCN had 2 fluid options, "FP" was used to designate the non-standard "Fire Preventive Fluid". The Fire Preventive Fluid is now the only fluid used in all LCN closers.
Q: Do LCN closers come with thru bolts?
A: The standard screw pack for an LCN closer is the SRT (Self Reaming and Tapping) screw. Thru bolts are an option, but must be specified on the order. There is no charge for them, but they do need to be specified.
Q: How do I get a Size 1 (ADA) closer to close against air pressure?
A: If an Size 1 (ADA) closer is set to 5 lbs. opening force, it will only have about 3 lbs. (60/70%) closing force. If the closer will not close against air pressure, but the ADA requirements have to be met, they may have to change to an automatic operator with a "power boost" option (Senior Swing) if there is that much pressure. If ADA does not have to be met you can increase the spring power on the end of the closer.
Q: What can be done for a door that will not close against wind pressure?
A: To correctly answer this question, we need to know how much more force is required to get the door closed. They could try turning the Rod & Shoe over (short side of shoe towards the hinge), or they may have to go to a sized closer (4016, 4026, 4116) instead of an adjustable closer. They could also try adding a 2nd closer on the door (one on each side of the door). This, however, will make the door harder to open. The answer to this application will be different for each installation.
Q: Does LCN sell a coupler to stack two 4040XP closers together?
A: LCN does not recommend this type of installation, and has never sold a coupler to do this.
Q: Can I use a Glynn Johnson 410 with a 4040 regular (pull side) mount?
A: ST-1630 is required when mounting a 4041 or 4040XP door closer regular (pull/hinge) side with a concealed GJ100 or GJ410 series over head stop.
Q: What special template (ST) is used with a 4040 Rw/PA mount closer and a GJ overhead stop?
A: Use ST-2776 when you have a 4040XP Rw/62A and Overhead stop 81, 90, 100, 410, 450 series - The standard PA shoe is replaced by the 62A shoe to lower the closer so that the arm will pass under the Glynn Johnson surface stop.
Q: Is there adjustment limits on the regulation valves of LCN manual closers?
A: The regulation valves are designed to adjust the flow the hydraulic fluid in the closer which regulates the door closing speed through various phases of the closing cycle. The regulation valves have limited adjustment and if opened up too far can cause damage to the seals and create hydraulic fluid leaks. The regulation valve assemblies are staked to provide some warning when the screws are at max adjustment but they cannot prevent the valve from being over adjusted.

The most common reason why users over adjust the regulation valve is to create more force to ensure the door latches during closing. Opening up or adjusting the latch speed will increase the latch speed but does not increase the closing force provided for latching the door, if more force is needed to latch the door the spring power should be increased.

The following information is a guide to ensure the regulation valves are not overly adjusted:

  • Shut off position: Shut off the valve by rotating it clockwise until it stops rotating
  • 1 turn out from shut off position: Very slow regulation / speed
  • 1 ½ turns out from shot off position: Slow regulation / speed
  • 2 turns out from shut off position: Normal regulation / speed
  • 2 ½ turns out from shut off position: Fast regulation / speed
  • 3 turns out from shut off position: Very Fast regulation / speed
  • 3 ½ turns out from shut off position: No Regulation, door will slam
  • 3 ½ turns out from shut off position: Risk of damaging seals – No impact to regulation or speed

    We do not recommend opening / adjusting the regulation valves more than 3 full turns from the shut off position.

    Further reading on "How do you adjust a door closer?" is as follows:

    All LCN and FALCON door closers will have 3 regulating valves and a spring adjustment. All closers with a "Delay" feature will have an additional 4th valve.

  • Back Check Valve, (valve #1 as specified in instructions) controls the back check intensity (3/32 allen wrench).

Turning the valve counter clockwise will give you a lighter backcheck. If the door must be stopped at a certain position, then a Cush arm can be used, or for more abusive applications, an overhead stop can be used.

The main speed is the area from the door in the wide open position down to the last 15°, or so, before the latch. Turning the valve clockwise will make the door close slower. Turning the valve counter clockwise will cause the door to close faster.

Clockwise gives the closer more closing power (which also makes the door harder to open), and turning the screw counter clockwise, will give the door less closing strength (and makes the door easier to open).

    To adjust closer to Factory Default Setting, turn all adjustments (back check, main speed, and latch speed) in fully clockwise, and then back out 1 1/2 turns counter clockwise.

    If the spring force adjustment is set to the very minimum force on the 1260 closers, the internal spring adjustment plate may rest in a safety area of the threaded spring adjustment rod. Simply open the door about a foot or so to engage the closer spring, and turn the adjustment screw about 6 turns clockwise and adjustment will be restored.

  • Q: Can you install a 4041 pull side at 180 degrees?
    A: The maximum opening is 120° with the 4041/4041XP standard templating on the pull side of the door er the installation instructions as seen here:

    Download File

    180° can be achieved with a PA mount per page 2 of the above installation instructions.

    Q: What is the valve on the back of a 4041/4040XP closer used for?
    A: The valve on the back of a 4041/4040XP closer is a "Back Check Selector Valve" that needs to be turned in on "Parallel Arm" mount applications ONLY, referred to only on the Parallel Arm Installation Sheet and re-routes the fluid in the closer so that it gets to the Backcheck Valve sooner, because in parallel arm installations the arm must otherwise travel farther before the fluid would reach the valve.
    Q: What is the Fifth Screw, Parallel Arm Shoe, spacer
    A: The Fifth Screw, Parallel Arm Shoe, spacer is insufficiently wide for all five holes in the parallel arm bracket to sit flat on to the soffit or perhaps on to the hardware compatible gasketing that has been installed.

    An example of this is when you would have a four and three quarter jammed up and you are installing a LCN 4040XP in a parallel arm fashion and if you were to study how wide the stop is and the spacing of all five holes of the parallel arm bracket you would determine that the 5th hole or the whole closest to where the arm shoe attaches to the bracket would not be flat on to the soffit and would cause the parallel arm bracket to potentially rock back and forth as the door was cycled through its open and closed cycle.

    please click the link to the installation instructions as seen here:

    Download File

    for a closer visual review of the concept that I am attempting to illustrate.

    A stop width of less than two and a quarter inch will require the spacer and it may be required to even modify the spacer or perhaps create a custom spacer if width of the stop prevents the entire space or block from fitting underneath the parallel arm bracket comfortably so that the screw can still pass through the countersunk hole in the parallel arm bracket in through the whole of the spacer.

    Q: Is the 4040 HEDA arm handed?
    A: The 4041/4040XP HEDA arm is handed because of the hold open feature. The regular EDA arm is not handed.
    Q: Can I use the 4040/4040XP in high traffic areas?
    A: The 4041/4040XP is a heavy duty door closer, designed for high traffic areas.
    Q: I have a LCN 4041 FP closer. What does the FP stand for?
    A: he FP in the part # is an old option for Fire Preventive Fluid. This designation is no longer used as the fire preventive fluid is standard. The direct replacement for the 4041 is the 4040XP closer as seen here:
