The Master Lock No. 15 Laminated Steel Padlock features a 2-1/2in (64mm) wide reinforced laminated steel lock body providing extra strength and a 1-1/4in (32mm) tall, 7/16in (11mm) diameter hardened boron alloy shackle for superior cut resistance. Dual locking levers provide extra pry resistance making it ideal for industrial applications and the non-rekeyable, 5-pin W15 cylinder helps prevent picking.
