Sturdy Key Labeling Available
Mechanical keys on a ring can be exposed to a great deal of physical abrasion. Polyester adhesive backed barcode labels simply will not last against constant wear. But a key labeled with an adhesive PermaLabel tag will last. The label has a laser marked sub surface under an aluminum oxide layer, which makes it abrasion resistant. Lifting of the label edge proves difficult due to the hardened aluminum construction.
