This is the black color of the Sepa easy replacement crescent lock. For the right side of 4-panel sliding doors and for 2-panel sliding doors. It is a universal replacement type and does not require drilling. The front and back height can be easily adjusted. Base dimensions: 82mm x 17mm Height to receiving bracket: 18.5mm - 30.5mm Pull-in dimension: 14mm - 26mm Mounting screw pitch: 30mm - 64mm ⭐︎I bought this because I wanted to replace the crescent lock at my home, but the size didn't fit, so it's opened but unused. The outer packaging is missing, so it will be shipped as shown in the first photo.
