The hooks are die cast under extreme pressure, which results in a very uniform material cross section void of internal defects, therefore creating a very consistent product with regard to finish and strength. To use, attach to your surface and use to secure Bungy Hooks or Shockcord in place. Width 20mm x 50mm, Height 27mm.
