Door lock Jania 72/50 mm for cylinder with lever - Z081, MP ZW 72Y5 J

Jania door lock Z081 is designed for use with a Euro-profile cylinder and an internal lever. The mechanism features a 72 mm backset with a 50 mm dimension referenced in the model name, enabling installation in standard residential and light-commercial doors.

It is compatible with wooden and metal door constructions where a cylinder-with-lever configuration is required.

Advantages

Its lever-operated latch offers smooth operation for everyday use, while its backset dimensions support standard door preparations. The unit is intended for single-leaf doors in homes and light commercial settings and is built to integrate with typical door furniture and strike plates.

How to use

Install the lock into a suitably prepared mortise in the door aligned with the 72 mm backset. Fit the Euro-profile cylinder through the lock case and secure it according to the cylinder manufacturer’s instructions. Attach the internal lever and exterior trim as required, then test latch operation by operating the lever and turning the key to confirm smooth engagement and release. Ensure the strike plate on the frame aligns with the latch for reliable closure.

Usage recommendations

For reliable performance, use a compatible Euro-profile cylinder of appropriate length for your door thickness and ensure the cylinder is properly secured. Periodically check mechanical parts for wear, lubricate moving components with a suitable lock lubricant, and verify alignment between the latch and strike plate. For security-sensitive installations, choose a cylinder with the desired security features and follow local building and fire-safety rules when fitting locks to exit routes.
