The Master Lock features a 7 feet (2.1m) car cover cable with laminated steel padlock. The braided steel cable design offers additional strength and flexibility. The padlock uses a 1-1/8 inch (29mm) wide laminated steel body for strength and reliability. The 3/16 inch (5mm) diameter shackle is 1/2 inch (13mm) long and made of steel, offering strong resistance to cutting. The warded single locking lever mechanism minimizes jamming from dirt and grime. The limited lifetime warranty provides peace of mind from a brand you can trust.
