Building a comms cabinet or expanding the one you already run comes down to parts that fit together properly, and this is where to start. The range covers server racks such as StarTech.com's four-post open-frame mobile model, plus the rack accessories that finish the job: top panels and blanking panels from Lanberg and APC to close gaps and keep airflow and cabling tidy. You'll also find automatic transfer switches (ATS) from APC, Salicru and Riello for switching power between two sources. We stock brands including Lanberg, StarTech.com, APC, Tripp Lite, Vertiv, Hewlett Packard Enterprise, Digitus, Equip, Phasak, QNAP and Salicru, so you can complete a build without juggling suppliers. Tell us what you're installing and we'll point you to the right parts.
