This Black Locking Cremone Bolt is based on a traditional, french styled door and window bolt. The simple Oval shaped door knob operates the two surface bolts, allowing the door or window to be opened easily in one action. The internal Centre Case has an additional grub screw locking mechanism, allowing the bolts to be locked into place for added security.
This bolt is supplied, as standard, for internal use only. But if you require access from both sides you can choose to purchase the set with an additional External Door Knob. Please note - the external door knob will only allow the bolt to be operated if the grub screw lock is not engaged. You cannot unscrew the grub screw from the outside.
Black Finish - this traditional satin black is baked in a high-temperature oven giving it an attractive, durable and corrosion-resistant finish. The finish is low maintenance when used internally, if used externally it will require more. In all cases we do recommend that it is wiped with a lightly oiled cloth periodically. This will help to remove surface dirt and restore it back to its original condition. This finish has been salt tested to 480 hours, which meets grade 5 British Standard.
Never use any form of metal cleaner or aerosol spray.
Supplied with guide blocks, a range of keeps and matching fixings. The screws supplied are hand finished, so please take care when fixing. Always use a pilot drill. You will need to trim the rods to size to fit your door or window.
