Marketing InformationThe Guy Gray Stainless Steel Recessed Dialysis Supply and Waste Box is an excellent option for configuring dialysis systems. This series of boxes (when equipped with valves) is designed specifically for reverse osmosis and deionized water mixed with dialysate saline concentrate. Made of corrosion-resistant stainless steel, these recessed dialysis waste and supply boxes have a 2-inch waste outlet and are available with either one or two valves (PVC or stainless steel) or valve holes only. The boxes can be easily secured to the wall via adjustable, stainless steel mounting flanges and some models feature a locking door.
