These are designed for use in super heavy duty applications and our customers find the extra long length to be so versatile. 16 inches of these are "hook" - the rough part which adheres down to the softer "loop" part. They have super heavy duty welded steel cinching rings, heavy duty nylon webbing, heavy duty thread, and they are also reinforced by diamond plated non-skid material to minimize slipping around your materials.
