Built around a central mortise gearbox, this multipoint door lock incorporates upper and lower extension sections on the same narrow faceplate. The lock case includes a square spindle follower, a euro-profile cylinder cut-out, and two separate rectangular projections at the door edge: an upper spring latch and a lower locking bolt. Long linking sections continue beyond the gearbox toward black end housings, giving the assembly a visibly different configuration from compact lock cases or gearbox-only products.
For door-system matching, buyers should verify the backset, handle-to-cylinder center distance, faceplate width, overall strip length, lock-case depth, and the positions of the remote locking sections. The direction of the latch, handing, end-section travel, and keeper arrangement also need confirmation. Door and frame routing must leave sufficient space for the central case and both extension sections.
An enquiry should include a dimensioned drawing or physical sample, door and frame profile sections, required operating direction, visible finish reference, quantity, and packaging requirements. CHIER can use this information to review the central gearbox and linked locking layout for an OEM or ODM project without assuming compatibility with another multipoint strip.
