Brooks’ indicative padlocks are the first to provide all the protection and reusability of classic ones, 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 products feature a bored hole that passes through the body and shackle. Applying a uniquely numbered, Brooks’ indicative seal through this cavity prevents it from being opened without first having to remove and destroy the seal on the padlocks, safely protecting your property.
