Product Overview

The FAPIM 3720B surface bolt is used for enhancing security and additional locking of doors in commercial and residential environments. Frequently installed on aluminum or steel doors, this bolt provides a manual locking solution where electronic controls are not required. Colored black, it is designed for visible surface-mount installation and is suitable for both new construction and retrofit projects.
