The Acme Pitbull Seal is a fixed length seal manufactured from two dissimilar materials. The locking mechanism is the same as the tried and tested Bulldog seal with an Acetyl insert to withstand freezing and boiling conditions and a polypropylene body for flexibility. The design includes rolled heat staking technology to secure the insert to the body, which provides clear evidence of tampering if forced open or cut. The seal has a large marking area within the loop of the seal unlike many large tag seals where the tag is on the outside which can be a problem in some applications. Manufactured with or without and easy break off point for easy removal this seal is ideal for securing vehicle doors, fire doors and restrictive work areas.
