ZW 1 Mortise Lock 73/57.5 Backset 57.5 mm Right-Handed 280x26 mm for Chinese Doors

Product Overview

The Zamek wpuszczany drzwiowy 73/57,5 ZW 1 cz. 280/26 PRAWY is a mortise lock specifically designed for Chinese-type exterior doors. Intended for use by door manufacturers, residential or light commercial contractors, and repair specialists, it features a right-handed configuration and comes with a lever mechanism. Installation is favored in residential settings and projects that involve upgrading or replacing locks on metal or security doors.

One differentiating feature of this lock is its precise specification for the backset (57.5 mm) and lock case size (280 x 26 mm), ensuring compatibility with non-standard, imported door formats where generic European locks do not fit. This targeted sizing reduces errors in procurement and on-site fitting, making the product particularly well-suited for bulk replacement orders and door OEM projects involving Chinese-sourced exterior doors.
