To minimize the overall change in elevation • Double Wall (DW) Sump Entry/Termination Fitting when installing a clam shell containment crossover, it is with Bonded Fiberglass Alignment Rings necessary to shorten one leg of the 450 containment elbow and the side outlet run of the containment tee. NOTE: Alignment rings can be bonded to a flat fiberglass surface only. DO NOT install on round or thermoplastic Refer to Table 10 for the maximum length that can be sumps. removed and for the minimum nipple length of both product piping and secondary containment piping. 1.
