Cylinder guard for deadbolt lock
A cylinder guard for a deadbolt lock having a face portion and an inner portion. The inner portion includes a radial flange and an axial flange created by forming the wall of the guard into a doubled portion. Indentations are formed in the axial flange which enhances the resistance of the guard to an attack upon the deadbolt. The guard also includes a tapered blow-deflecting portion between the inner portion and face portion. A crush zone may be formed between the inner and face portions to attenuate the energy from an attack that is transferred to the axial and radial flanges. A method for making the guard includes stamping a body from steel strip using a multi-station press.
