The load column of the type I hanger is electro- galvanized. For highly corrosive conditions, hanger is completely neoprene coated except the load column for type F which is stainless steel. Cold set at the factory upon request. Spring and casing are fabricated of steel and are rugged and compact. Piston cap serves as a centering device or guide maintaining spring alignment.
Casing protects the spring from damage and weather conditions.
All welding is done in strict accordance with the ANSI Code. Securely attach hanger to the building. Attach lower hanger rod and turn the load coupling until the load indicator is positioned at the desired setting indicated on the load scale plate. If it is not, the hanger should be readjusted to the hot position. No other adjustment is necessary.
