Matrix Innovations Stainless Quad Lock

Due to the quad multi-point system, simply tighten the alarm up to the nearest 90 degrees on the buzzer bar, undo the collar, take the alarm off, turn it round to face the front and then screw it back on again. The design also allows the alarms to be removed from bars for storage or if you want to swap between different buzzer bar set-ups.

Available as a complete unit, or just the base unit for switching set-ups.
