Cylinder Operated Flush Bolt

The Z1870 is a cylinder operated flush bolt for fitting to the inactive leaf of a pair of doors to prevent unauthorised operation. It should be fitted to both the top and the bottom of the inactive leaf. It is suitable for use on aluminium and steel doors. A 360° turn of the key throws or retracts the hardened hex-section bolt, and the key is only removable when the bolt is in a positively locked or unlocked position.
