Brass Oval Knob Operated Espagnolette Bolt

Polished brass espagnolette bolt with a plain oval turn knob. Fitted to secure a door or window top and bottom by simply turning the knob. 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.
