Use this double Panamax Rackmount Kit to mount your M5100-PM or MR5000 power supply in your standard rack and keep your power cable runs to your rack-mounted gear short. This allows you to use shorter cables, virtually eliminating voltage drops and noise in your power.
I needed a rackmount kit for my Panamax M5100-PM to put into a rack enclosure. This was a hard-to-find OEM kit. It's around on eBay and other sites but costs 4 to 5 times as much, as it is discontinued. I saw that there was some stock at a decent price so I purchased it. It arrived on time and was as described.
