National Marker N197962 Polished Brass Door Surface Bolt 2 in

Product Description

The National Marker N197962 is a 2-inch polished brass surface bolt from the Gallery Series, designed for securing casement windows and French, twin, or Dutch doors. Constructed from solid brass with a polished brass finish, this surface bolt features an extra-long throw that locks into position via a tension spring, providing reliable hold without the need for additional hardware adjustments. The concealed base design prevents contact with and damage to wood door surfaces, making it well suited for finish carpentry applications.

The 2-inch throw length suits standard door and window stile widths. Includes both universal and mortise strike options, offering flexibility across a range of door frame configurations and installation conditions.

Installation Notes

Surface bolts of this type are typically installed by carpenters or general contractors using standard hand tools including a drill, screwdriver, and level.
