Door Security | Sheffield Window Centre

An intruder seeking to break open a door may choose to "attack" the lock cylinder using tools of the trade such as drills, pliers, picklocks and other lock-forcing tools. So we fit the CISA Astral S Cylinder (manufactured by Ingersoll Rand) in combination with the Multi Hook-Lock. This cylinder has every security feature, such as anti-snap, anti- pick, anti-drill, anti-bump and is designed to prevent an intruder gaining access to your home.
