These tie down anchors have loads of uses. As bike benches rarely have enough, if any, tie down points, we always fit a number of these on our benches. Before these came on the market we used 'U' bolts, but they were always getting in the way when not in use. When not being used the tie on point is easily removed, leaving an unobtrusive anchor point. They can also used inthe back ov vans or in trailers to tie down bikes. Please be carefull not to ratchet against the quick release mechanism at an angle. These anchors are great but care must be used. If in any doubt feel free to e-mail or telephone us for advice on the safe use of this excelent product. The kit comes with mounting bolts, washers, nyloc nuts and two anchors points
