A narrow ribbed lever and raised pivot housing define this manually operated window sash lock. The handle follows a mostly straight profile with a rounded end, while an exposed crescent-shaped cam moves beside the pivot to engage a separate keeper. Its elongated oval-ended base includes two recessed fixing holes, and the images show black and white exterior color options. Crescent lock and sweep lock are established terms for this sash-locking format.
Specification should begin with the relationship between the moving cam and the mating keeper. Buyers need to verify the base dimensions, fixing-hole spacing, cam projection, keeper height and available sash overlap. Lever sweep, operating direction and profile clearance also require confirmation, especially where the handle sits close to glazing beads, frame returns or adjacent hardware. The visible color options should be treated as finish variants rather than proof of material or coating type.
For replacement work or OEM/ODM review, submit a window-section drawing, front and side dimensions of the mounting area, the existing lock and keeper samples, handing or rotation requirements, selected color, quantity and packaging instructions. These references allow CHIER to assess the mounting pattern and lock-to-keeper geometry before quotation.
