These 200 U-Type constant spring supports were modified to increase their installed height by adding a secondary plate and angles, which will be welded to the structural beam. The constants range in size from 25" to 27" in height, 52" to 67" in length, and 25" in width. Their load capacities range from 10,300 lb. to 13,000 lb. with vertical movement ranging from 3" to 4-1/2". All constants were fabricated from A-36 carbon steel, and went through standard load and travel testing per MSS Standards prior to shipment.
