Description

The DELTANA 12SB3-UNL is a heavy-duty surface bolt finished in unlacquered bright brass, designed for use on doors, gates, and frames in both residential and light commercial applications. Surface bolts of this type are installed by carpenters, finish contractors, and facilities maintenance professionals to provide secondary latching or locking on inactive door panels, Dutch doors, and double-door assemblies. The bolt measures 12.6 inches in length and is constructed from solid brass, delivering the corrosion resistance and load capacity expected in architectural hardware applications. The unlacquered finish allows the brass to develop a natural patina over time.

This surface bolt is suited for interior and exterior door applications where a secure, surface-mounted slide bolt is required. Typical installations include double entry doors, French doors, barn doors, and utility or storage room doors. The heavy-duty designation indicates reinforced construction appropriate for high-cycle or higher-load environments compared to standard residential surface bolts. Installation is straightforward and does not require specialty tooling beyond a drill and screwdriver.

Installation Notes

Installation is typically performed by a finish carpenter or general contractor using a drill, screwdriver, and standard template layout tools. Mount the bolt body to the face of the door stile and align the strike to the frame or floor before fastening. Ensure the door is fully plumb and square before marking strike locations to avoid binding. The unlacquered brass finish should not be coated after installation if natural patina is desired.
