Q: A while back I purchased the CP1000 Pivot Set and am just now beginning the installation. I have two questions I hope you can help me with. 1) There is a rubber boot covering the bearing housing of floor bearing. Does that rubber boot stay on the bearing housing when grouting the floor bearing into the floor? 2) The bottom arm does not sit all the way down on the spindle like it think it would. It stops about 1/4 inch above what looks like a seat on the spindle. Is that the way it is suppose to be? Thank you, George H.
A: This order is almost 2 - years old and it seems you are like me. Far far too many projects to do and not nearly enough time.

I have never heard of a rubber boot as you have described. What would be the purpose of this rubber boot that you mentioned?

Based on your description of the spindle and the bottom arm, it is standard or typical that the spindle does not completely see itself covered by the bottom arm itself and it is that spindle which will nest into the bottom arm, in other words seat itself, within the rectangular prep in the bottom arm. It is normal for a bit of the bottom spindle to show and is in no way completely concealed by that arm itself.

If you think that this is a point of concern, by all means forward to us or reply to this email message, with photographs of the hardware so that we can further eliminate the possibility that there was anything errant with the hardware that you have been shipped.

Q: I have attached two photos to show the seat on the spindle that I thought the bottom arm should rest on, but does not because it stops on the shaft about a 1/4 inch above the seat. The photos also show the rubber boot or cover on the bearing housing. Thank you for help. George Hoggan
A: Indeed the bottom arm does not sit all the way down on top of the shoulders of the bottom thrust bearing assembly. Please review the link to the installation instructions as seen here:

You also asked about the rubber boots that is included with the pivot assembly. Yes indeed you are to leave the rubber boot on as the intention of the rubber boot is to allow an easier removal of the entire floor bearing assembly in the case you should ever, in the future need to do this, after the unit is grouted into place.

Q: what's the shipping weight for this item ? can you also include the dimensions of the package when it's shipped please.
A: An approximate shipping weight for the CP440 Dorma Pivot Set would be 4 lb and the box would likely be about 10 inch by 6 inch by 6 inch
Q: I have a CP440 Dorma set for a door that was given to me. I dont have the Floor Bearing (7471K), or the top pivot portion that is set in the header. I actually want a hinge set that will "return to center" which this one wont do from my understanding. Is there a pivot set that I can retrofit to this door (since its already been fitted with CP440) that will make it a "Return to Center" swinging door?
A: There are no pivots that will return to center but you could install a floor closer or perhaps an overhead concealed closer.

Would either of these be options you would be interested in?

Q: Can you direct me to a these “closers” you mentioned? I just need to see how it works/functions. In that case the CP440 will be fine, and I can order the needed parts from you. I just don’t know how these closers work.

Update: Actually I see what the closers are now, however I am hoping that this door can pivot both ways. Is there any type of closer that can close the door from swing both ways? I hope this makes sense, I want the door to swing open no matter which way you enter from, either side. Then I want the door to swing back closed. Is this possible? Thank you for your help.

A: Yes - overhead concealed door and floor closers can both be double acting and I would draw your attention to the following documents:

  • For floor closers we have the Dorma BTS80 which is a fully capable floor closer that will not only double act but obviously self center and available with all of the potential options that will permit you to have the correct arrangement of hardware to suit your field conditions. That catalog can be seen here:

  • For overhead concealed closers we have the Dorma RTS88 which too is a fully capable overhead concealed closer that will double act, return to center and give you all of the possible options that you would require giving your particular field conditions. That catalog can be seen here:

    The distinct advantage of both of these products is that they are concealed, self closing as they return to center. You will find this exact door closer used in countless commercial installations where they are subjected to very demanding application requirements. Please do a deep feel free to reach out to us directly if you have any questions on installation or product application

  • Q: Thank you very much for the information. Due to the cost of those concealed top and floor closers, and the size of the foot print of the installation, I have decided to attempt to retrofit the Bommer 7811 into the existing door. The installation should be OK since the CP440 was less intrusive into the door, the Bommer Spring Hinge should be able to be installed after mortising the door further. I saw your review on the Bommer 7811 on YouTube and figured it was the right choice, thank you! Regards, James
    A: It did not occur to me that the Bommer version would be compatible for your application only because it is capable of handling only about 25% of the load capacity of the door that the original pivot wood handle. Please tell me - how heavy is your door?
    Q: I think this door is probably about 60 to 75 lbs. It’s a solid wood 32” x 78” x 1 3/8” door. It’s an old replica “Movie Theater” door with a circular window, red vinyl and brass rivets and brass push plates. It has tons of style which is why I want to reuse it in my Media Room in my basement between the Media Room and a Laundry room. It’s heavy to me, but not too heavy for the spring clip hinge (up to 90 lbs I think). The original hardware installed to the door was the CP440 which was probably overkill. Also I think it was a part of a set of double doors if that matters. Was pulled out of some rich guys Home Theater room and I am reusing it.
    A: Thank you for providing the weight and size of the door - while I believe that the door is heavier than you estimate I don't believe that it would be too heavy for the Bommer 7811 as seen here, listed only in the different finish options:

    Click Here

    This unit will handle the weight, will be double acting and self centering and give you an option to hold the door open should you want to have unimpeded access to the room such as for cleaning.

    This unit has been on the market for several decades possibly over a century - I do not know the earliest instance of where this hardware occurs in a Bommer catalog but this company is about 150 years old or thereabouts and I would fully trust in the quality and caliber of the American-made version of this double acting spring pivot.

    Q: I need to know where the dorma cp440 is made in?
    A: The country of origin for the Dorma CP440 is the United States (Pennsylvania I believe).
