Deltana 4FBS3 Flush Bolt Heavy Duty 4 Inches Bright Brass

Product Description

The DELTANA 4FBS3 is a heavy-duty flush bolt designed for door hardware applications requiring a clean, concealed fastening solution. Measuring 4.1 inches in length, 1.2 inches in width, and 0.8 inches in height, this flush bolt installs into the edge of a door to secure it in the closed position without exposed surface hardware. The bright brass finish provides a polished appearance suited to interior architectural installations. It is installed by finish carpenters, door hardware specialists, and general contractors working on residential or light commercial door assemblies.

Flush bolts like the 4FBS3 are typically used on inactive door leafs in pairs of doors, french doors, and double-door entry systems where one door must remain stationary. The unit ships individually and is sold per each, making it straightforward to order for single-door or multi-door projects. The bright brass finish coordinates with matching door hardware sets in the same finish family.

Installation Notes

Flush bolts are installed by finish carpenters or door hardware technicians using a router or chisel to mortise the bolt housing flush into the door edge. Ensure the door is properly supported and all finish work is complete before mortising. Align the strike plate or floor cup with the bolt throw before final fastening. Follow local building codes for door hardware requirements on egress and fire-rated assemblies.
