Lock out locks are the bread and butter of any LOTO program. LOTO locks are color coded and come in two different sizes. The locks different colors makes them easy to use for different functions. We carry Masterlock, American Lock, and Brady Padlocks. Keep a steady supply on hand for new employees, lost , used or damaged locks. Most of our locks come single keyed as to limit access. However for those special situations dual keyed locks are still available. Locks provide peace of mind for supervisors and employees who work with hazardous energy. Locks with longer shackles can reach more difficult isolation points.
