The postals-gtdmb is a flush-mounted surface postal lock designed for secure, controlled access in mail and package delivery applications. The unit features a solid metal faceplate that resists tampering and corrosion, and a keyed mechanism built for dependable daily operation. Overall dimensions are 6 inches high by 6 inches wide by 1-7/8 inches deep, with a cutout opening of 5-7/8 inches height by 5-7/8 inches width to fit standard back box installations. The flush-mount design allows the unit to sit evenly within the surrounding surface for a clean, built-in appearance. This lock is installed by locksmiths, low-voltage technicians, or general contractors working in residential and commercial access control projects.
The postals-gtdmb suits multi-tenant residential buildings, commercial mailrooms, gated entry systems, and any installation requiring a durable flush-mounted mail access point. The precise cutout dimensions accommodate standard back box openings, making it compatible with new construction and retrofit scenarios. Its corrosion-resistant metal faceplate holds up in both interior and exterior-protected enclosures. This unit is appropriate for low-voltage access control environments where a clean faceplate finish and reliable keyed entry are required.
Designed as an OEM-style replacement or new-installation postal lock fitting standard back box cutouts sized for 5-7/8 inches by 5-7/8 inches openings in residential and commercial mail delivery systems.
Installation is typically performed by a licensed locksmith, low-voltage technician, or qualified contractor. Power down or de-energize any adjacent access control or low-voltage systems before beginning work. Verify the rough-in cutout matches the 5-7/8 inch by 5-7/8 inch opening requirement before mounting. Secure the faceplate evenly to avoid binding the keyed mechanism during operation.
