LOB 72/50 Mortise Cylinder Lock INOX Stainless Steel Universal L/R 72mm 50mm 100kg

Product Overview

The LOB 72/50 mortise cylinder lock is a universal lock for both left- and right-handed installation, built for external and internal doors supporting up to 100 kg in residential or commercial properties. Its faceplate and strike plate are manufactured from INOX stainless steel for enhanced durability and corrosion resistance in variable environmental conditions.

Unlike generic mortise locks, this model uses a zamak (zinc-aluminum alloy) latch and bolt, both nickel-plated for increased wear resistance and smoother operation across its rated durability of 200,000 cycles. This specific feature reduces replacement cycles and maintenance risk, making it a solid choice for B2B buyers managing door hardware for multi-unit residential buildings or commercial refurbishments.
