The 11” diam. double-flanged housing of this device supports an 8” (200) diam. cleanout and ensures no loading is transmitted to connected pipes. The upper flange suspends the housing and cleanout in areas surfaced with concrete, black top or earth fill. The bottom flange is to be set in a ring of concrete poured below ground in areas surfaced with asphalt or earth fill. Both jacket and cleanout are made of Duco coated cast iron. A secured cast iron cover tops the device. The cleanout’s taper thread plug is a bronze.
