    tie down brackets
    by Joseph from Sebastian, Florida on June 13, 2016
    To the knowledgeable boat owner, he or she would known that the swivel brackets were also necessary but sold seperately. As I have suggested before, any additional parts needed to accompany original item purchased should be suggested at time of order.

    Good Brackets to Modify Older Boat Trailers
    by Joseph from Cookeville, Tennessee on August 12, 2011
    I used these Bolster Brackets to add Bunk Boards to an antique tube/pipe frame boat trailer with rollers. They are substantial as far as strength and thickness is concerned. Galvanized coating could be a little thicker but anything other than stainless steel is eventually going to develop some surface rust anyway. All in all, I couldn't be happier with the quality of this product.
