Narrow Lock Box 90/22 Metal High Weldability for Limited Profile Door Frames

Product Overview

The narrow lock box 90/22 is a metal enclosure designed for installation in doors where the profile does not allow standard recessed lock placement. This product is utilized by manufacturers and installers working with door frames in residential, commercial, or light industrial settings, particularly where space constraints are present in the door profile.

Its most distinguishing feature is high weldability, which greatly simplifies integration with various metal door profiles during fabrication. By eliminating compatibility issues and reducing installation complexity, it is particularly suited for bulk procurement by OEM door manufacturers or metalworking shops handling custom frame designs.
