The Chameleon Adaptable Multipoint Lock is a versatile repair solution designed for the maintenance and restoration of UPVC and composite door systems. Its unique three-part modular construction allows for easier transportation and handling compared to traditional one-piece units, while remaining straightforward to assemble on-site.
This lock is engineered to serve as a reliable replacement for many failed or obsolete multipoint systems. It features a combination of 2 mushroom cams and 2 roller cams, providing a balanced performance of physical security against forced entry and effective compression for weather sealing. The inclusion of a matching set of keeps ensures that the locking points can be properly aligned and secured within the existing door frame.
Typically employed by maintenance professionals and locksmiths, this unit operates with a standard latch and deadbolt central gearbox. It is designed for use with standard euro cylinders and handles with 92mm centres. The 16mm faceplate is the standard specification for the majority of modern plastic and composite doors, making this a highly adaptable component for retrofitting and repair applications.
Version-specific operation: CH10583 (28mm) is listed for lift-lever operation; CH10584 (35mm) supports lift-lever or split-spindle operation. A lever/pad handle alone does not turn the 28mm version into a split-spindle lock. CH30046 is the matching mushroom/roller replenishment set; its keep arrangement must suit the replacement assembly.
Compare the original backset, 92mm centres, faceplate/profile, locking-point positions and replacement keeps before fitting. Croppable extensions are not a guarantee of interchangeability with an unrelated centre case or the original frame keeps.
