ASSA ABLOY One System WC 78/55 Bathroom Lock 8mm Universal Hand INOX Rounded Faceplate

Product Overview

ASSA ABLOY One System WC 78/55 is a bathroom door lock with an 8 mm spindle and rounded stainless steel faceplate (20/235 mm), commonly installed in residential and commercial restrooms. The mounting holes feature special notches that provide extra resistance against screw loosening, ensuring stable installation over time. The faceplate is made from INOX (stainless steel) for added durability in humid environments such as bathrooms.

The standout feature of this lock is its universal handing, which accommodates both left- and right-handed doors without reconfiguration. This eliminates a common procurement risk, minimizing specification errors and simplifying inventory for facility managers and contractors. It is particularly suited for bulk bathroom fit-outs in hotels, office buildings, and apartment complexes.
