Surface-Mounted Door Lock Adjustable Backset 50-60mm White for Wooden Doors with Cylinder

Product Overview

The Zamek wierzchni 50-60 biały z wkładką is a surface-mounted lock designed for wooden doors with a thickness of up to 60 mm. Manufactured in Poland, it serves residential and light commercial applications where retrofitting or additional security on existing doors is required. The product includes a matching white finish cylinder and provides basic, key-operated security for interior and exterior doors in these settings.

What distinguishes this lock is its adjustable backset, allowing the distance from the cylinder axis to the lock face to be set between 50 mm and 60 mm. This feature reduces installation errors and ensures compatibility with a wider range of door designs and preexisting holes, which matters for facility managers or contractors refurbishing diverse building stock. It is especially suited for maintenance teams and small-scale housing upgrades where standardization and adaptability are priorities.
