Metalplast-Częstochowa RZB-5 Mortise Roller Lock 22mm Faceplate for Aluminum Steel Doors

Product Overview

The Zamek wpuszczany RZB-5 dormas 22 is a mortise roller lock designed for use in aluminum and steel joinery. Its construction supports installation within commercial and industrial doors where durability and consistent performance are required, such as office buildings, production facilities, and public infrastructure. Manufactured by Metalplast-Częstochowa, the lock features a faceplate width of 22 mm and is intended for professional door fabrication or refurbishment projects.

The most notable differentiator of the RZB-5 is its 22 mm faceplate and dormas sizing, which directly matches common European aluminum and steel door profiles. This compatibility significantly streamlines procurement and installation for mass production or retrofit scenarios, where precise fit reduces the risk of returns and on-site rework. It is especially suited for door manufacturers and bulk procurement in construction supply chains dealing with non-wooden door assemblies.
