When I towed the Safari to and from the interior shop I was concerned that the cargo straps wouldn't hold if I had to make a quick stop. These skid clamps were fabricated based on a design of Stu Fields, a Safari dealer. Stu normally has these available for sale but he was out of inventory and he offered me some photos so I could fab my own.(website: www.vksupportservice.com).
They hold the helicopter much more securely without the need for any straps or ropes.The bolts go through the trailer bed and thread into a stainless nut welded onto a strap that is fastened to the underside of the trailer.
