Securing a box, rack or other enclosure may require a lockable cam latching mechanism. Plastic and zinc plated steel cams added to a wide variety of keyed locking mechanisms prevents unwanted tampering and theft. Cams are available that include a built-in stopper and are differentiated by lengths from 25 to 68 mm and widths from 13 to 19 mm. Height dimensions include forward or reverse offset bends.
