Deltana 4FBS10B Flush Bolt 4 Inches Oil Rubbed Bronze

Product Description

The DELTANA 4FBS10B is a heavy-duty flush bolt designed for installation into the edge of a door to secure it against a frame or floor strike without requiring an exposed surface-mounted mechanism. The bolt slides flush within the door edge, keeping the hardware nearly invisible when not engaged. Finished in Oil Rubbed Bronze, it suits applications where dark, warm-toned hardware is specified. At 4.5 inches in length and 0.2 pounds, it is lightweight enough for single-door installs yet built to handle the daily demands of commercial and residential entryways. Carpenters, door hardware installers, and finish contractors are the typical trades working with this type of hardware.

The 4FBS10B fits applications where a paired or inactive door leaf needs to be held in place without a visible surface bolt. Common scenarios include double-door entry systems in commercial offices, residential interior French doors, and exterior double-door units where one leaf is held stationary. The Oil Rubbed Bronze finish coordinates with door levers, hinges, and escutcheons in the same finish family.

• Oil Rubbed Bronze finish for a dark, warm-toned aesthetic consistent with coordinated hardware sets

Compatibility

Designed as an OEM-style replacement or new-install flush bolt for standard residential and light commercial door edge applications where a 4-inch class flush bolt is specified.

Installation Notes

Flush bolts are typically installed by carpenters or door hardware professionals during door prep or finish hardware installation. The door edge must be mortised to accept the bolt housing before installation; confirm mortise dimensions match the bolt body before cutting. Disengage any door hardware and ensure the door is properly supported before routing or chiseling the mortise. Follow applicable local building codes for door hardware requirements on egress and fire-rated door assemblies.
