Sioux Chief’s Expansion Tank Support Kit comprises a simple, strong, steel bracket to secure expansion tanks. The system is designed to secure expansion tanks to wall studs and is useful for apartment installations where the water heater is located in a closet. Expansion tank kits are sold 10 to a case in two sizes: Kit 598-0210 has a 32.5” stainless-steel snap-lock band to secure 2-gal. tanks, while Kit 598-0213 has a 45” stainless-steel snap-lock bank long enough to wrap around a 5-gal. tank. Each band threads through a 16-gauge galvanized steel bracket that fastens to the stud wall with two 2” screws.
