The cases are made of strong ABS plastic and supplied in a knock-down form that can be assembled in seconds with just a screwdriver.  Slots are moulded into the top and bottom covers to provide good cross-flow ventilation while moulded PCB standoffs allow printed circuit boards to be mounted directly onto the covers. The cases are a practical alternative to the traditional heavy metal cases and are much lighter when mounting in racks and easier to machine when fitting connectors, controls or panel meters etc. 

Various sizes are available i.e. 1 unit (44mm), 2 unit (88mm) or 3 unit (132mm).  All sizes are 200mm deep and are available in black or beige.
