Deltana 8SB3-UNL Surface Bolt 8 in Heavy Duty Unlacquered Brass

Product Description

The DELTANA 8SB3-UNL is a heavy-duty surface bolt finished in unlacquered bright brass. Surface bolts are used to secure inactive door leafs, gates, and panels at the top or bottom edge, providing a positive latch point without a separate lockset. This unit measures 8 inches in bolt throw length and is constructed from solid brass, making it suitable for both interior and exterior applications where corrosion resistance and appearance are priorities. The unlacquered finish allows the natural brass to develop a patina over time, a common specification in restoration and high-end architectural work. Installation is handled by carpenters, finish hardware contractors, or general tradespeople during rough or finish door hardware phases.

The 8SB3-UNL is appropriate for residential and light commercial door applications, including double-door entry sets, French doors, bi-fold door pairs, and cabinet enclosures requiring a secondary securing method. It is sold individually and is well suited for projects specifying solid brass architectural hardware in an unlacquered bright brass finish. The overall package dimensions are 9 inches in length, 1.9 inches in width, and 1.7 inches in height.

Installation Notes

Surface bolts are typically installed by finish carpenters or door hardware contractors using standard woodworking screws and a drill or screwdriver. Verify door frame alignment before marking strike locations to ensure smooth bolt engagement. No specialized tools or code permits are generally required for surface bolt installation on interior doors; exterior or fire-rated assemblies should be confirmed against local building codes before installation.
