The Master Lock No. 22 Laminated Steel padlock, Keyed Alike – multiple locks open with the same key – features a 1-1/2in (38mm) wide laminated steel body to withstand physical abuse and a 5/8in (16mm) tall, 14in (6mm) diameter steel shackle provides strong cut resistance. Ideal for applications requiring basic tamper resistance, a warded locking mechanism minimizes binding from dirt and grime.
