Trimco 3820X3810.630 – Frequently Asked Questions

1) Does the Trimco 3820x3810 flush bolt work on a fire rated pair of doors?
The 3820x3810 is a UL semi-automatic flush bolt set for metal doors. If the fire rated pair also requires a fire bolt at the top of the inactive leaf, the set to order is the 3820x3850, which is the same semi-automatic flush bolt paired with the 3850 fire bolt rather than a second standard bolt.
2) What is the difference between a semi-automatic and an automatic flush bolt on a pair of doors?
With the semi-automatic 3820x3810, the inactive leaf bolts are projected by hand and then release automatically when the active leaf opens, so the inactive door is not tied to the active leaf for throwing the bolts. The automatic version in the same family, the 3810x3810, projects and retracts off the movement of the active leaf. Both are in Trimco's 3800 Series and both are offered for metal doors, so the choice comes down to whether you want staff to deliberately set the inactive leaf or have it happen on its own.
3) What does the 3820x3810 part number actually cover, top and bottom?
The designation pairs two bolts for one inactive leaf: the 3820 semi-automatic bolt and the 3810 bolt, sold together as the set for a metal door. That is why the Trimco 3800 Series numbers read as a pair, such as 3810x3810 for the full automatic set or 3820x3850 when the top position is a fire bolt.
4) What finishes does the Trimco 3820 semi-automatic flush bolt come in?
Ten finish choices: bright brass 605, satin brass 606, oil rubbed bronze 613, dark oxidized satin bronze 613E, matte black 622, bright chrome 625, satin chrome 626, bright stainless 629, satin stainless 630, and a 626/630 satin chrome with satin stainless combination. For a building already standardized on 626 or 630 lever trim, the matching flush bolt faceplate is available in the same BHMA number.
5) Will elderly or low-strength users be able to close an inactive leaf with these flush bolts?
The 3800 Series bolts are built to need very low closing force to secure the door, and Trimco's patented design uses about a third fewer parts than a conventional flush bolt, with the key components in stainless steel. Trimco also calls out a low noise level, which matters in hospitality and multifamily corridors where a pair of doors gets cycled at night.
6) Can I change the flush bolt trim later without replacing the whole bolt?
Yes. The 3800 Series uses interchangeable trim kits, so the face trim can be swapped if a finish gets changed out during a renovation without pulling and replacing the bolt mechanism itself in the door edge.
7) Are Trimco 3820 flush bolts suitable for commercial traffic or are they a residential item?
This is commercial hardware. Trimco lists the 3800 Series flush bolts for commercial and industrial buildings, hospitality, multifamily and mixed-use, and office buildings, and the product is classed commercial rather than residential.
