Review on Industrial Safety TRADESAFE Lockout Tagout Kit Refill - 7 Keyed Differently Red Safety Padlocks, 1 Key Per Lock, Guaranteed Lock Out Tag Out Security - Trustworthy Lockout Tagout Brand And Company by Marty Wainwright

These locks feel substantial (all lockout locks look plasticky) and were the best value for my needs. These are all keyed different, which is important so others cannot energize the source you are working on without your knowledge! I was of course worried then that the only key could be easily lost, but what is nice is until you lock the U-bolt the key cannot come out. Easy to hang multiple locks (unlocked) with their respective keys inserted. I would not hesitate to buy this brand again.
