T54C Cylinder Replacement Kit

The new T54C T-Knob Cylinder Replacement Kit replaces original CompX/National T-knob pin tumbler cylinders. You no longer need to replace the entire T-Knob lock, just replace the non-functional cylinder. Our replacement cylinder is all brass construction for increased durability. This is a 5-pin cylinder and can be easily keyed to match your existing 4-pin or 5-pin systems including our T37 T-bolt lock for metal bank drawers and our other National keyway products.
