Skim-Master is a non-corrosive, large capacity automatic surface skimmer featuring a round, tamper-proof access cover, self adjusting 8" weir with stainless steel spring for added strength (SP1071), dual outlets, and threaded internal connections for pressure testing. The optional float/ bypass valve provides a main drain-thru-skimmer system and an automatic safety bypass for low water conditions. No glue is used in manufacturing, promoting maximum strength and longevity. Both the SP1071 and SP1070 Series provide a knockout overflow port that guards overflow or pool water refill. All Skim-Master Series Skimmers are available with Float Valve Equalizer Kit to meet specific NSF commercial requirements
