The DrainKing Waste Valve is a great addition to any establishment. The Waste Valve features a cast red brass body with dual Teflon seals, stainless steel ball, stainless steel clamping ring and a stainless steel flat strainer. There is a "clear through" opening, meaning there is no need to disassemble if snaking it required. The Valve has an industry standard "sealing" angle that fits flush to standard stainless steel sinks. 1/4 turn fully opens and closes the Valve. - Stainless steel/brass - Drain rate 12 gpm - Height 4 in - Width 11-5/8 in - Sold per each
