Trimco 3825LX3815L626630 Flush Bolt Pair Ul Wood Doors

Product Description

The TRIMCO 3825LX3815L626630 is a matched pair of long UL-listed semi-automatic flush bolts designed for installation on active and inactive leaves of wood doors. Semi-automatic flush bolts engage the frame head and floor strike automatically when the door closes, without requiring a separate manual throw. This pair ships with two bolts to cover both the top and bottom of an inactive door leaf, providing secure two-point latching. The 626 satin chrome face finish pairs with a 630 satin stainless steel body, making the hardware suitable for environments where corrosion resistance and finish consistency matter. Installation is performed by licensed door hardware or finish hardware contractors.

Semi-automatic flush bolts of this type are used on pairs of wood doors in commercial and institutional applications — corridors, conference rooms, vestibules, and stairwell entries where a double-door opening requires one leaf to be held stationary. The UL listing makes this hardware appropriate for use on fire-rated door assemblies where listed hardware is required by code. The long bolt length accommodates doors with greater header and floor clearance than standard-length flush bolt applications.

Key Features

• Semi-automatic operation — bolt extends upon door closure without manual actuation
• UL listed for use on fire-rated wood door assemblies
• Sold as a pair covering both top and bottom bolt locations on an inactive leaf
• 626 satin chrome finish on exposed face hardware
• 630 satin stainless steel body for corrosion resistance
• Long bolt format for doors requiring extended reach to head and floor strikes

Compatibility

Designed as an OEM-style flush bolt replacement or new installation component for pairs of wood swinging doors requiring UL-listed semi-automatic flush bolt hardware.

Installation Notes

Flush bolts are installed by qualified door hardware technicians or carpenters familiar with door prep and fire-rated assembly requirements. The door must be prepped with the correct mortise pocket and strike locations per the manufacturer template before installation. On fire-rated assemblies, verify that the complete door assembly — including frame, door, and all hardware — carries the required label and listing. Confirm the door leaf thickness and edge preparation match the bolt dimensions prior to install.
