Deltana 12EFB3 Extension Flush Bolt Solid Brass

Product Description

The DELTANA 12EFB3 is a 12-inch extension flush bolt designed for use in door hardware applications where a concealed or semi-concealed bolting mechanism is required. Constructed from solid brass with a bright brass finish, this flush bolt provides corrosion resistance and long-term durability in both interior and exterior door assemblies. At 0.73 pounds, it is a full-length unit measuring 12.6 inches in length, 1.2 inches in width, and 1.5 inches in height. Licensed door hardware installers and millwork contractors specify this type of hardware on paired doors, French doors, and inactive door leafs where top and bottom bolting is standard practice.

Extension flush bolts are commonly used on the inactive panel of double doors in residential and light commercial settings. This unit is suited for wood door applications where the bolt barrel is mortised or surface-mounted into the door edge, providing top or bottom engagement into a strike plate set into the frame or floor. Its solid brass construction makes it a fit for environments where finish consistency with other brass door hardware is required. Sold individually, it is a direct hardware supply item for door installers, finish carpenters, and architectural hardware distributors.

Installation Notes

Extension flush bolts are typically installed by finish carpenters or licensed door hardware installers. Before installation, confirm door stile width is sufficient to accept the bolt barrel without compromising structural integrity. Mortise or surface-mount routing should be completed before hanging the door. Verify strike plate alignment at the head jamb and floor prior to final fastening to ensure smooth bolt operation.
