KARO KP-40 TW (041-068/K30195350) Latch Bolt Lock 16mm Drop-Latch for PVC Profiles

Product Overview

The KARO KP-40 TW (041-068/K30195350) is a latch bolt lock designed for installation in plastic profiles, commonly used in window or door systems within residential and light commercial buildings. Its construction supports both left- and right-handed mounting, providing flexibility for fabricators and installers working with profile-based assemblies in controlled indoor environments.

What distinguishes this model is its drop-latch (zasuwka opadająca) mechanism, which improves security by automatically engaging when the door or window is closed, minimizing user error and reducing call-backs for faulty latching. This feature is especially relevant for OEM window and door manufacturers who require reliable, low-maintenance locking solutions for volume production.
