Protect your door hardware cylinders from vandalism using the Adams Rite MS4043 cylinder guard. These hardened steel rings make it virtually impossible to extract the cylinder using pipe wrenches, special pliers, or other leverage devices. Because the standard brass mortise cylinder is a soft spot in door security, cylinder guards are an essential addition to your building.
