ZW 4 Mortise Lock for Chinese Doors 68/60 Left-Handed 240x30mm Additional Bolt

Product Overview

The Zamek trzpieniowy do drzwi chińskich (68/60) cz. 30/240 ZW 4 P/L is a mortise lock specifically designed for Chinese-manufactured doors, with a faceplate measuring 240x30 mm. Commonly used by door installers or maintenance professionals in residential and light commercial settings, this lock features additional bolt locking to enhance security. Please note, this lock is not reversible and is manufactured specifically for left-handed doors.

A key distinguishing feature of this model is its purpose-built sizing to fit the 68/60 door standard found in many imported Chinese doors, eliminating compatibility issues that occur with European standard locks during replacement or retrofitting. The left-handed orientation also reduces installation errors in projects with strongly specified swing directions. It is particularly recommended for distributors, service companies, and contractors specializing in the maintenance or refurbishment of properties with Chinese door stock.
