Enclosure parts include all components that can be installed onto motherboards and computer cases used in an office environment, such as panelboards and power distribution boards, as well as operator panels and control panels. This category features a wide range of product types; external parts such as enclosure handles and window frames; parts for case interior such as power supply holders, circuit boards, DIN rails, ground bars and copper bus bars; parts for fastening the enclosure and for providing portability, such as mounting brackets, racks, stands and board casters; parts for stable enclosure operation, such as enclosure heaters, heatsinks and louvers; and also maintenance parts such as insulation putty and silicone gels, among others. Enclosure parts sometimes need to be added or replaced; properties such as voltage and size should be carefully considered when performing these tasks.
