## Long description

The Latch Bolt Cylinder Lock LOB KD50M is a brass mortise cylinder designed for use with latch and bolt mechanisms in residential and light commercial doors. The lock features a solid brass body crafted for installation into standard cylinder housings and mortise fittings, providing mechanical key-operated locking without electronic components. Its dimensions and configuration make it suitable for retrofit or new installations where a reliable mechanical cylinder is required.
Advantages
The brass construction offers corrosion resistance and consistent mechanical performance over time, while the mortise design allows secure integration with existing latch and bolt assemblies. The cylinder is compatible with common door hardware standards, enabling straightforward replacement or upgrade of mechanical locking components. Its simple, mechanical operation ensures low maintenance and predictable behavior under normal usage conditions.

How to use
Install the cylinder into the door’s mortise or existing cylinder housing according to the door hardware manufacturer’s instructions, ensuring the cylinder length matches the door thickness and locking mechanism alignment. Insert and turn the key to check smooth engagement with the latch or bolt; adjust housing or mounting screws as needed to eliminate binding. Periodically operate the cylinder to confirm reliable movement and, if applicable, lubricate with a dry graphite or manufacturer-recommended lubricant to maintain function.

Verify door thickness and existing housing dimensions before purchase to ensure proper fit.
