The constants range in size from 22″ to 30″ in height, 35″ to 85″ in length, and 12″ to 31″ in width. Their load capacities range from 1,800 lb. to 20,800 lb. with a vertical movement ranging from 7″ to 11-1/2″. All constants were fabricated from A-36 carbon steel and painted with a 3-coat paint system. Each constant went through standard load and travel testing per MSS Standards prior to shipment.
