Trimco TRI-W3917-12-626 – Frequently Asked Questions
1) Will the Trimco W3917 flush bolt work in a hollow metal door?
Metal doors are exactly what the W3917 is built for. The 3910 Series covers both wood and metal openings, and the W3917 is the metal-door version of the manual flush bolt. If the inactive leaf is a wood door, order the wood-door model in the series instead, since the mortise cutout and body differ between the two.
2) Do I need a top and bottom flush bolt on a pair of doors, or just one?
A pair with no center mullion normally takes two manual flush bolts on the inactive leaf, one at the head and one at the sill, so that leaf is pinned top and bottom and the active leaf can latch into it. The W3917 is sold as a single bolt, so a full opening is two of them, and the top one usually gets the longer rod while the bottom runs short. You also need a strike at each end: a dust proof strike in the threshold for the bottom bolt and a frame strike at the head.
3) Is a manual flush bolt like the Trimco 3917 the right choice, or should I use automatic or constant latching bolts?
Manual is the right call when the inactive leaf stays shut most of the time, a storage room, an equipment room, a corridor pair opened wide only for deliveries. Someone has to reach up and throw the finger by hand, which is fine on a leaf nobody touches. If the inactive leaf gets opened routinely, or the opening is fire rated and the code official wants the leaf to self latch, an automatic or constant latching bolt is the better fit because it sets itself when the door closes. The W3917 is a manual bolt with positive spring action that holds the throw locked or unlocked.
4) Are Trimco 3910 Series flush bolt rods stainless steel?
The finger, the part you actually work with your thumb, is stainless steel, which Trimco calls out as unique in the category. The body is a high density extrusion. That combination matters on the piece that gets flexed thousands of times over a building's life, which is why these hold up in corridors and service pairs where a cast finger eventually snaps.
5) Can I use the Trimco 3917 flush bolt on apartment or hotel door pairs?
It is a commercial grade bolt, and multifamily, mixed use and hospitality are among its stated applications alongside office and industrial buildings. For a property manager standardizing across a portfolio, the useful part is that one model covers all your metal leaf pairs, with rod length picked per door height and one finish carried across the whole building.
