L-Slide covers are used for applications in which the contents of a plastic housing may have to be accessed repeatedly. Most often the L-base (or cover) is secured by fasteners once in place. The L-cover may slide in on and fasten to welded rails. Another option is to utilize the tongue and groove method. The internal electronics may be mounted to the 4-sided partial enclosure, or the L-slide component. The L-slide enclosure works well when the PCB has large connectors protruding from opposing sides.
