Brooks Tamper Indicating Padlocks


Unlike traditional padlocks that can be opened and re-closed without any evidence of tampering, Brooks Indicative Padlocks feature a bored hole that passes through the body and shackel. 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.

Brooks offers a complete line of solid brass tumbler pin locks.  Precision-crafted out of solid brass, our locks withstand inclement weather conditions and are available with brass, stainless steel or heat-treated stainless steel shackles.

Locks are available keyed alike, keyed differently, master keyed and grand master keyed.  We can also key our locks to most popular keyways (ie: Master, Corbin, Yale, Best and others).
