Please provide us with a detailed drawing of the <br />fitting configuration you require. <br />Fiberglass Manway Extensions <br />Tank entry in high groundwater conditions and/or deep burials <br />may require the use of manway extensions. When properly bolted <br />to a tank -mounted manway, the manway extension will provide a <br />watertight access route to the tank interior. Fiberglass manway <br />extensions of 22", 30" and 36" diameters are available in 2' lengths. <br />Each manway extension includes a gasket and set of nuts, bolts <br />and washers. <br />Fiberglass Manway Riser <br />The optional fiberglass manway riser provides a non -corroding <br />passage from a manhole box and cover (traffic areas require <br />reinforced concrete road surface) down to the tank manway. <br />The manway riser is available in 30" thru 54" lengths in 6" incre- <br />ments. It consists of a 48" diameter tube, open at one end, partially <br />closed on the other end with a 22-1/2" centered square hole with <br />rounded corners. <br />If buoyant conditions can exist and the tank has more than one <br />manway riser, contact Tank Technical Service for proper tank <br />anchoring recommendations for the installation. <br />B <br />2 <br />8" <br />– <br />M222 -j <br />C <br />3 <br />8" <br />– <br />M223-8 <br />D <br />3 <br />8" <br />90° <br />M223-8 <br />E <br />3 <br />8" <br />120° <br />M223- <br />F <br />4 <br />8" <br />90° <br />M224-1 <br />G <br />5 <br />8" <br />90° <br />M225-1 <br />A <br />1 <br />Center <br />– <br />M301 <br />B <br />2 <br />12" <br />– <br />M302-13 <br />C <br />3 <br />12" <br />– <br />M303-11 <br />D <br />3 <br />12" <br />90° <br />M303-1, <br />E <br />3 <br />12" <br />120° <br />M303-1 <br />F <br />4 <br />12" <br />90° <br />M304-1 <br />G <br />5 <br />12" <br />90° <br />M305-1 <br />A <br />1 <br />Center <br />– <br />M361-( <br />B <br />2 <br />15" <br />– <br />10362-1; <br />C <br />3 <br />15" <br />– <br />M363.1: <br />D <br />3 <br />15" <br />90° <br />M363-1: <br />E <br />3 <br />15" <br />120° <br />M363-1 <br />F <br />4 <br />15" <br />90° <br />M364-1 <br />G <br />5 <br />15" <br />90° <br />M365-1 <br />Fiberglass Manway Extension <br />j�eNn4 <br />FITTING <br />CONRIGURATIONS <br />AAt o) <br />Reinforced Concrete <br />Rebar 8" Center <br />24" X 24" Manhole Box with Cover <br />Bolayers) <br />Both Ways (22 layers) <br />(not supplied) <br />opo <br />•o• •o•o ao •o•o <br />481D —> <br />42' <br />Riser <br />Standard <br />22" Manway <br />A <br />A <br />2" x 4" x 4'0" Min. or <br />Equivalent Wood <br />Required to Support Riser <br />Notes: <br />1.
