LOB TB51 Surface-Mounted Cylinder Lock Single-Cylinder Brown 32?64mm Door

Product Overview

The LOB TB51 surface-mounted cylinder lock provides secure latch-based locking for doors with thickness between 32 and 64 mm, typically used in residential and light commercial environments. Its body and strike plate are manufactured from stamped steel and powder-coated for corrosion resistance, with alternative galvanic finishes available for custom orders. Each package includes three cut keys for consistent access control.

What distinguishes the TB51 is its single-cylinder latch mechanism, offering straightforward installation and operational simplicity compared to double-cylinder locks. This reduces installation time and minimizes compatibility risks for installers managing bulk door hardware upgrades. The TB51 is particularly suited for procurement in residential retrofit projects and small-scale commercial renovations where durability and ease of installation are priorities.
