They look beautiful and rubust in the brochure. What does not fit in practice. The parts are not broken the edges. When I had mounted the davits and my small rubber boat about 3O kg with the outerborder about 17 kg hochzog the Davits have bent the same! According to product description, they are calculated for 130 kg! Can not continue this product. If you want pictures of the bent davits I can gladly e-mail you.
