This pair of "spring steel" brackets provide a very strong means of attaching Lateral Trunk, Lateral Hip/Thigh or Lateral Knee Supports to a solid surface (solid seat, solid back or a seat pan). The brackets are a treated metal providing the tensile strength of steel while having limited flexibility to prevent metal fatigue. The array of sizes provide the ability to clear almost all cushion heights as well as have significant in/out or up/down adjustability
