Satin Chrome Knob Operated Espagnolette Bolt

Satin chrome espagnolette bolt with a rectangular shaped backplate and a stepped edge design oval knob. Used for securing a door or window top and bottom by simply turning the knob. Turning the knob throws the rods, locating them into the staples and plates fitted to the door frame and floor. Turning the knob again disengages the rods, freeing the door to open. This bolt has a grub screw type lock located in the handle back plate which, when tightened, presses against the rod underneath locking it in position. Although the bolt features this basic locking mechanism, a key locking espagnolette bolt would be more suitable on an external door or window which is regularly used. Suitable for a maximum door height of 3000mm.
