To meet this demand, engineers at Southco, Concordville, Pa. (, developed the CM line of cam locks. The removable-core design gives OEMs a range of options to choose from and lets them mix and match interchangeable housings to satisfy their customers' needs.

Access, for example, can be though wing-grip hand latches, keys, or Phillips, slotted or hex tools. Sealed-cam versions meet NEMA-4 and IP66 standards. Locks can rotate clockwise or counterclockwise, with 90 or 180° cam rotations. Mounting options include nuts for metal doors, spring clips for fast assembly, nuts with washers for outdoor applications, and nuts with prong washers that clinch into low-density materials. Locks can also be overmolded or reversible and have custom logos.

Sizes range from 1.6 to 57.2 mm (0.63 to 2.25 in.). Mini-sizes work with grips as small as 21.5 mm (0.85-in. tall) with just 14.9-mm (0.59-in.) diameter flange exposure on the front panel and as little as 16.4-mm (0.65-in.) cam protrusion from centerline. Locks handle up to 180-N ultimate loads; with the mini-sized locks handling 160 N.
