The Fisher 2210WB Pre-Rinse Unit is wall-mounted with 8 inch adjustable centers (eccentrics adjust from 7-3/4 to 8-1/4 inches). It is made with stainless steel seats, seat screws, and handle screws. The 36 inch hose features a spring action flexible gooseneck, stainless steel external jacket, and 3 ply fiber reinforced internal rubber hose. The ultra spray valve is the lowest energy user (1.15 GPM @ 60 PSI) and is engineered to last because there are no 'O' rings to leak. The wall bracket adjusts from 2-12 inches.
