Each Tamper-Proof key ring from Key Systems comes engraved with its own unique serial number for ID purposes. The string of letters and numbers serves as a tracking device for conducting audits on both the rings and their keys.
Kitchen or utility knives, prison shop tools, small firearms, medical equipment and cash tills can be secured to one of the high-security rings for both portable and fixed security.
The Tamper-Proof Key Rings are made of solid and braided stainless steel and have male and female ends. One end is closed inside the other and a crimping tool is used to squeeze and tighten the connection.
