This slim mortise lock case is arranged around two projecting hook bolts positioned at separate points along an extended faceplate. The hook-shaped locking elements provide the clearest visual distinction from the round-bolt configurations used on other multipoint lock bodies. A euro-profile cylinder opening is located in the lower section of the case, while the upper operating area includes a circular hub opening for connection to the door handle mechanism.
The narrow body and long silver-toned faceplate are intended for recessed installation within the door edge. Before selecting this lock, buyers should compare the backset, handle-to-cylinder center distance, overall faceplate dimensions, lock-case depth, hook spacing, hook projection, and operating direction with the existing door preparation. Handing and the position, depth, and shape of the matching keepers also require confirmation because the hooks must enter and retain correctly within the frame-side components.
For quotation review, provide a dimensioned drawing or physical sample, door and frame profile sections, required handing, finish reference, order quantity, and packaging specification. These details allow CHIER to assess the lock geometry and prepare an OEM or ODM proposal without treating the unit as a universal replacement.
