Trimco 3825L626630 – Frequently Asked Questions

1) Is the Trimco 3825L flush bolt for wood doors or hollow metal doors?
The 3825L is the wood door version. Trimco's 3800 Series semi-automatic flush bolts are made for metal or wood doors, so if the inactive leaf on your pair is hollow metal, you want the metal door version of the series instead, not this one. Mortising a wood-door bolt into a steel door is not a substitution you can make in the field.
2) Do I need to order both the 3825L and the 3815L for a pair of doors?
Yes. Semi-automatic flush bolts go into the inactive leaf as a top and bottom set, and Trimco pairs the long 3825L with the 3815L for that reason. One bolt on its own only secures one end of the leaf, which leaves the door free to flex and pull out of the frame at the other end. Order the set for each inactive leaf you are securing.
3) What is the difference between a semi-automatic flush bolt and an automatic flush bolt?
Both hold the inactive leaf of a pair. An automatic flush bolt throws and retracts on its own as the active leaf operates, so nobody has to touch the inactive door. A semi-automatic bolt like the 3825L retracts automatically when the active leaf opens, but the bolt is thrown by hand at the inactive leaf. Trimco builds the 3800 Series in both, so if your opening needs the inactive leaf to release without anyone reaching for it, specify the automatic version of the series rather than the semi-automatic.
4) Is the Trimco 3825L flush bolt rated for commercial use?
It is a commercial product, and it carries a UL designation as part of the 3825L Long UL semi-automatic flush bolt. Key components are stainless steel and the body is steel, which is what carries the cycle count on a busy pair of doors in a school, hospital corridor, or apartment common area.
5) Will a flush bolt hold an inactive leaf that people keep pushing on?
The 3800 Series design is built around low closing force, so the leaf secures without slamming it, and Trimco's patented construction uses about a third fewer parts than a conventional flush bolt with the key components in stainless steel. Fewer moving parts and a quiet throw is what keeps these serviceable on doors that get leaned on daily. For an opening where the inactive leaf gets pushed as an exit, a flush bolt is the wrong device, that opening needs an exit device on both leaves.
6) What finish does the Trimco 3825L semi-automatic flush bolt come in?
626/630, satin chrome with satin stainless steel. That is the standard satin look on most commercial openings, so it sits alongside 626 lever trim, closers, and push plates without a mismatch. If the rest of your building is bright brass or oil-rubbed bronze, this is not the finish that blends in.
7) Can I change the exposed trim on a Trimco 3800 Series flush bolt without replacing the whole bolt?
Yes. The 3800 Series uses interchangeable trim kits, so the face trim can be swapped rather than pulling and re-mortising the bolt body. That matters if you standardize a building on one bolt and need a different look on a lobby pair, or if a face plate gets damaged and you would otherwise be cutting the door again.
