Ilco 1" Turn Knob Cylinder For Adams Rite

Both the inside and the outside of a door fitted with a double-cylinder deadbolt need a key to unlock it. This type of double-door lock system is commonly used in business and manufacturing settings. A single-cylinder deadbolt has only one side with a key-operated locking mechanism. Deadbolt door locks are a good way to beef up your home's security. This high-quality brass turn knob cylinder is useful and is made strongly by Adams Rite, which is a very dependable brand. If you’re trying to change your double to a single-cylinder lock, a turn knob cylinder will be required, and brass is a good choice of material for this device.
