This kit provides all of the hardware and sheet metal parts to convert any THD UniValve, BiValve-30, Deco-36 or Flexi-50 to a 5-space, 19" rack-mount unit. The kit includes a new bottom panel and right and left "wings", all made from black powder-coated steel, and a black powder-coated steel face panel, complete with THD Logo. All screws are included, as are 4 isolation washers to protect the face of the unit from the rack-mounting screws.
