This window sash lock series is built around a manual lever and an exposed crescent-shaped cam that rotates around the central pivot. The visible configurations include a slotted flat mounting plate, a raised rectangular housing, a rounded rectangular base and an oval-ended plate with countersunk fixing points. These base profiles provide different installation layouts while retaining the same clear lever-to-cam operating principle for engaging a separate keeper on the sash or frame.
Selection should be based on the complete locking geometry rather than the handle shape alone. Buyers need to compare mounting-hole spacing, base dimensions, lever sweep and available clearance around the profile. The cam projection, engagement direction, sash overlap, handing and keeper arrangement must also be confirmed to prevent interference or incomplete locking after installation.
For a matching review, provide the window section drawing, current lock and keeper samples, installation orientation and the required operating direction. Quotations should also state the selected base configuration, visible finish, order quantity and packaging requirements. CHIER can use these references to assess replacement matching or an OEM/ODM version without assuming compatibility from appearance alone.
