Strict tolerances provide you with the ultimate in strength and durability. Our patented Tamper-Proof Key Ring® technology provides your most valuable assets with an added layer of protection. 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 Security Asset Manager™ (SAM) electronic cabinets.

As a one time use security device, our rings verify that items taken from a safe match the items returned to that safe. 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.
