Fit the tall shackle of these locks around bulky parts, such as thick chains—it has over 1" of vertical clearance. Made of hardened steel, the shackle is strong enough to withstand bumps and scrapes without denting. With these locks, you can set your own combination and change it at any time. Since they don’t require a key to unlock, they’re useful when multiple people need to access secured equipment. They’re also handy if you need to switch the combination often.

Style C locks have a dual-locking shackle, so they prevent attempts to force them open from prying, shimming, or tapping because both ends of the shackle lock inside the body. Made of zinc, the body is corrosion resistant, but it's not as strong as a steel body.
