Brooks Indicative Padlocks are the first to provide all the protection and reusability of classic padlocks, along with the tamper indication/deterrence feature of Brooks’ single-use seals. Unlike traditional padlocks that can be opened and re-closed without any evidence of tampering, Brooks’ Indicative Padlocks feature a 1/8” diameter bored hole that passes through the body and shackle. Applying a uniquely numbered, Brooks’ indicative seal through this cavity prevents the padlock from being opened without first having to remove and destroy the seal.
