30 Amp Power Supply (PSU) Underslung mounting

It has also been enlarged for depth, to allow slight clearance between the surface and the power supply body to ease fit and removal and to help cooling. The non-terminal end of the bracketry (The 2nd Piece), has been scratch designed and is intended to remain fitted permanently to the mounting surface. To remove the PSU for maintenance, simply undo the two wood-screws from the terminal cover end and slide the PSU out of the non-terminal end bracket. The mounting lugs are designed to accommodate countersunk 5mm diameter woodscrews. Recommend drilling a 2mm pilot hole into the cardboard.. er, I mean, the bottom of the Lack table top. There are two versions of the switch cover. One has a hole for a…
