Hager Profile Half Cylinder ZAY50994 with 2 Keys 40x20x40

Control cabinet and switchgear doors often need a simple, reliable locking solution that can be operated from one side only. The Hager Profile Half Cylinder ZAY50994 provides exactly that: a mechanical half cylinder with two keys, sized 40 mm in length with a 10 mm cam offset, ready to fit standard profile cylinder openings.

Tips

When replacing an existing half cylinder, measure the A-dimension (length from the front face to the centre of the cam) and B-dimension (cam offset) to ensure a proper fit. The ZAY50994 is keyed different, so each cylinder has a unique key combination; order additional cylinders if you need keyed alike functionality.
