The defining element of this multipoint mortise lock case is its split twin-piece latch assembly, which projects through a long brushed faceplate near the upper end. The narrow lock body also includes a square spindle follower and euro-profile cylinder opening, providing separate interfaces for handle and cylinder operation. Multiple countersunk fixing holes are distributed along the faceplate, and a rectangular opening is positioned below the latch section.
System matching should begin with the existing door preparation rather than external appearance alone. Buyers need to compare the backset, handle-to-cylinder center distance, faceplate width and overall length, lock-case depth, spindle position, latch projection, and handing. The corresponding keeper arrangement and any connection points for upper or lower locking elements must also be confirmed before approving a sample.
For an OEM or ODM assessment, provide CHIER with a dimensioned drawing or reference sample, door and frame sections, opening direction, required finish, projected quantity, and packaging instructions. This information supports a practical review of the lock-body geometry and reduces the risk of mismatch during installation or replacement.
