Q: I am a site manager at a (94) unit condominium. There are two 36" exterior doors that are vulnerable during high winds. I installed this crash chain on a recently replaced door to prevent damage to the door, the hinges and the door frame. During recent high winds the cast metal loop or eye that is mounted to the frame failed. The screws held as they were supposed to. The chain and spring were undamaged. I have replaced the cast metal lops with 1" bolt/screw down cargo loops usually sold at industrial, hardware establishments, tractor supply and places that cater to the welding fabrication business like people that repair and construct trailers. This seems to be a cheap fix for the manufacturer of these crash chains but I don't have a clue as to who to pass on my experience to.
A: Thanks for sharing and also consider these pieces of hardware as more robust solutions to this problem:

Q: Hi Rich, I’ve been researching crash chains and came across your website, watched a video on the Trimco 4048 heavy-duty crash chain, I need advice we have a self storage facility in Waco Texas that I’m having issues with all the exterior doors. The wind has been catching them and self close is not holding. We have installed rubber bollards on the ground to stop them but I think these crash chains may be the solution. Would like some advice from you if you could get back with me. We have 13 48” exterior steel doors and 13 36” exterior steel doors. I need to know which model and size would be best solution for our situation. We will be planning on drilling out the tops of the doors and put Through bolts for better securing as you suggested. Thanks, look forward to hearing back asap... I will be in Waco at our facility next Thursday and would like to get these ordered so I can arrange getting them installed while I am there on site.
A: We need to enter this order immediately to have the material arrive to you by next Thursday. We will arrange the order so as to reflect the length of the chain compatible with each of your two door widths. I can contact you at any time to process this order,
Q: What size do l need for a 36 inch wide door
A: The size needed for a 36” wide door would be a 25-1/2” length chain. The Trimco 4048 is adjustable from 20” to 30-1/2” which allows it to compensate for doors from 2 foot to 4 ft wide. The Trimco 4048 Crash Chain features extra heavy-duty solid welded steel twist chain designed for heavy commercial doors. Heavily cast brass plates with heavy compression springs at each end.
Q: Question, are your crash chains made of stainless steel, Do you have any made of stainless. Why you may ask? I live on a canal.
A: Is theThere are no crash chains that are made of stainless steel however, given the relative and expensive cost of the item, I would simply replace them as the corrosion, which would likely not interfere with the proper operation and safety of the unit for several years, began to impede the unit's ability to perform safely.
Q: We have a 36' exterior door, 1 3/4 thick with glass starting 4" from the top of the door. Any crash chain suggestions, especially due to the glass?
A: It would not suggest nor consider a crash chain as a safe or reliable means to responsibly control an 1-3/4” thick door with glass. I would suggest using an overhead stop such as the It would not suggest nor consider a crash chain as a safe or reliable means to responsibly control an 1-3/4” thick door with glass.

Q: Why does the picture shown w/the chain guard already being installed on the door & header seem to be COMPLETELY DIFFERENT than the handy reference guide/installation instructions (which ODDLY are the SAME EXACT instructions & drawing for EVERY MFRs "Install Instructions" found anywhere online, BUT ALL videos & pictures show it being installed from Door Header to Top of Door; NOT Door Jamb to Top of Door like ALL instructions seem to show)?
A: I would answer that simply by saying theres more than one way to install these. I find residential units are mounted to the jamb and to the door and commercial units are typically mounted from the header to the door.
