We are local lake goers who know boating. There are times when you are the only one on the boat that knows how to tie a knot, making it very inconvenient when you are also the captain. ​ Rope Lock was designed for this! Anyone can now use the device to secure the boat to the dock or throw down some fenders at the perfect height every time. Not only is Rope Lock used for Docking, Bumpers, it is great for Anchoring, Sailboat/Rigging, Camping, Gardening, Construction, Towing, Dog leashes and even used as a Horse Safety Tie with our Equine version!
