Slide-In Chassis Housings consist of a 4-sided cover and an L-shaped slide-in chassis. This is ideal for circuit boards with protruding connectors on opposing sides because the PCB can be easily mounted to the chassis which is then slid into the 4-sided cover. Keyways minimize the need for fasteners and in many cases only a single flush-mount screw is needed to securely lock the 2 parts together. This is the most assembly-friendly solution for single PCB plastic housings. ABS and PC-ABS are the preferred materials for these custom enclosures.
