Trimco 3910 626 – Frequently Asked Questions
1) Will Trimco 3910 flush bolts work on hollow metal doors, or are they only for wood doors?
Both. The 3910 Series manual flush bolts are made for wood or metal doors, so the same part covers a hollow metal pair in a stairwell and a wood pair in a corridor. That matters for a property manager standardizing across a building with mixed door construction, since one series and one finish carries across both.
2) What is the difference between the Trimco 3910 and the 3910N flush bolt?
The faceplate. The 3910 ships as a dust proof strike with a face plate; the 3910N is the dust proof strike with no face plate. Pick the 3910 when the strike sits in a finished threshold or floor and you want the visible trim ring; pick the 3910N when the strike is being set into a prep where a face plate is not wanted or another cover handles it. Both are offered in the same ten finishes.
3) Do I need a manual flush bolt or an automatic one for my pair of doors?
A manual flush bolt like the 3910 is thrown and retracted by hand at the inactive leaf, so somebody has to reach up or down and move the finger. That is right when the inactive leaf stays latched most of the time and only opens for moving furniture or equipment. If the inactive leaf has to release on its own every time the active leaf opens, you want an automatic or constant-latching flush bolt instead, not this one. Manual bolts are the common choice on commercial, multifamily, hospitality, and office pairs where the second leaf is opened rarely.
4) What finishes do Trimco 3910 flush bolts come in?
Ten, and they cover most architectural specs you would be matching to: 605 bright brass, 606 satin brass, 613 oil rubbed bronze, 613E dark oxidized satin bronze, 622 matte black, 625 bright chrome, 626 satin chrome, 629 bright stainless steel, 630 satin stainless steel, and a 626/630 satin chrome / satin stainless combination. Every one of those is offered on both the 3910 and the 3910N, so the faceplate choice does not limit your finish. 626 and 630 are the usual commercial defaults if you are matching existing lever trim and hinges.
5) My doors are a non-standard height, can I get longer flush bolt rods?
Custom rod lengths are available on the 3910 Series, and the series can be custom ordered for special applications. That covers tall openings where a standard rod will not reach the head strike. Get the door height and the bolt location settled before ordering, because a custom rod is not a stock swap.
6) What does the dust proof strike on the Trimco 3910 actually do at the floor?
The bottom bolt on a pair drops into a strike set in the floor, and that hole collects grit, which is what stops a bolt from seating. The 3910 dust proof strike has a spring loaded plunger that stays flush with the floor until the bolt pushes it down, so the pocket stays closed and clear between uses. That is the difference between a bolt that throws every time and one a maintenance tech has to chip out twice a year.
7) How many Trimco 3910 flush bolts do I order per pair of doors?
Two per pair in the normal case, one at the head and one at the floor, both installed in the inactive leaf. The active leaf gets the lock or exit device; the inactive leaf is the one that gets bolted. If your inactive leaf is only being secured at the top, a single bolt is all you need, but a pair of doors held at both head and threshold is the usual commercial arrangement. Order the same faceplate option, 3910 or 3910N, and the same finish for both so the leaf reads consistent.
8) Can I get Trimco 3910 flush bolts to match the finish on doors that already have Trimco trim?
The 3910 Series is offered in most architectural finishes, and the ten stocked options run the standard BHMA numbers, 605, 606, 613, 613E, 622, 625, 626, 629, and 630, plus a 626/630 combination. Because those are BHMA finish codes rather than a Trimco-only naming scheme, matching is a matter of reading the code off what is already installed and ordering the same number. A building standardized on 630 satin stainless gets 630 bolts on both faceplate versions.
9) Will the finger on a Trimco 3910 flush bolt hold up in a high-traffic building?
The finger is stainless steel, which Trimco states is unique to their flush bolts, and the body is a high density extrusion. The failure point on cheap flush bolts is a soft or plated finger that wears or snaps where a maintenance tech pushes it; stainless is what keeps that from being an annual replacement in a hospitality or multifamily corridor. Positive spring action locks or unlocks the throw completely, so the bolt does not sit half-thrown.
