Print Literature Sheet (PDF)

Our patented Tamper-Proof Key Ring® technology provides you with the ultimate in strength and durability. These high security stainless steel rings cannot be opened without detection thus preventing asset removal or substitution. They may serve on their own as a high strength key ring or in conjunction with our electronic key safe as an added layer of protection for your most valuable assets. As a one time use security device our rings verify that items taken from a safe match the items returned. Tamper-Proof Key Rings® come in five different sizes of solid or flexible style and are used to secure assets from keys and utility knives to medical equipment and cash tills.

Secure With Tamper-Proof Key Rings®
Key Ring Serial Number

Unique ID

No two key rings are alike and are uniquely identified by a permanent serial number. Each ring is engraved before distribution to allow for detection in the event it is tampered with or replaced.




Key Ring Smooth Seal

Smooth Seal

Our crimping tool closes both solid and flexible rings with a smooth seal. This allows for a 360 degree use of each ring without the hindrance of a raised seal.



Organize Keys and Assets With Color Coded Control

Color Coded Control

Also available, five options of color coding tags that slip easily over the rings providing unique identification and key separation.

Colors: Red, Orange, Yellow, Green, Blue, and Assorted (Orders Come in Packages of 50)



Our specified tools eliminate the need for welding and other awkward methods. Proper tool management also provides an added level of security in controlling those allowed to alter assets contained on a ring.
