Solcor Adjustable Hook is a cleat hook that allows variation in cord length and tension. It can be used to hook cord or rope to a fixed point – or to fix tarpaulins to the side of a vehicle. The Adjustable Hook is also suitable for use in a marine environment. These hooks are compatible with 6mm and 8mm bungee cord or rope. Simply pull bungee cord through the barrel and tug excess cord down to lock it into place.
