The Chameleon Adaptable Multipoint Lock is a versatile repair solution designed to replace failed locking mechanisms in uPVC and composite doors. Its unique 3-part modular construction makes it significantly easier to transport and handle compared to traditional full-length locks, while maintaining structural integrity.
This system features a combination of two hooks and two rollers, providing a balance of high security and effective weather compression. The inclusion of croppable locking point extensions ensures that the mechanism can be precisely adjusted to fit a wide range of door heights, making it an ideal choice for maintenance and repair applications where an exact original match may no longer be available.
Application and Compatibility:
- Designed for doors with a standard 16mm wide faceplate.
- Supplied complete with matching keeps for a full system replacement.
- The manufacturer identifies CH10579 (35mm) and CH10581 (45mm) for lift-lever or split-spindle operation. CH10577 (28mm), CH10578 (30mm) and CH10580 (40mm) are listed for lift-lever operation. Do not assume every backset supports nightlatch operation.
- Commonly used as a universal repair part to restore security to existing door sets.
Whether used for a new installation or as a comprehensive replacement part, this Chameleon lock provides a reliable and adjustable security solution for external door systems.
Version check: the stocked 55mm reference CH30165 is not identified in the manufacturer model table examined. Confirm its spindle function before specifying outside key-only entry.
The manufacturer measures the upper hook 347-847mm and lower hook 377-877mm from the spindle on the illustrated modular range; compare the actual supplied version with the guide before cutting. CH30047 is the existing matching hook/roller replenishment set, not an additional requirement for the complete lock kit.
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.
