Deltana 18EFB19 Extension Flush Bolt 18 in Solid Brass

Product Description

The DELTANA 18EFB19 is an 18-inch extension flush bolt designed for use in door hardware applications requiring a concealed or semi-concealed locking mechanism. Constructed from solid brass with a black finish, this flush bolt installs into the edge of a door to engage a strike in the floor or head jamb, securing inactive door leaves in pairs or providing supplemental locking on single doors. At 18 inches in length, it suits tall doors where standard-length flush bolts fall short. The solid brass construction resists corrosion and provides the structural integrity required for commercial and residential architectural hardware installations. Locksmiths, carpenters, and finish hardware installers typically handle this type of work.

The 18EFB19 is suited for residential and light commercial door applications, particularly on double-door sets, French doors, and entry systems where the inactive leaf must be held securely at both the floor and head. Extension flush bolts are commonly specified on wood and hollow-metal doors where a rod-actuated mechanism provides clean aesthetics without exposed surface hardware. The black finish integrates with dark hardware sets and is appropriate for both interior and exterior door applications where finish consistency is a design requirement.

Installation Notes

Extension flush bolts are installed by carpenters or finish hardware professionals and require mortising or routing into the door edge to recess the bolt body. Power down any access control or electrified hardware tied to the door before beginning work. Refer to the door manufacturer's hardware prep specifications and applicable building codes for strike placement at the floor and head jamb. Do not overtighten mounting fasteners into solid brass bodies, as the material can be damaged by excessive torque.
