If you have a deck railing, then odds are VERY good that the Hold It Mate system was designed for your deck.  Hold It Mate attaches directly to the spindles (round or square, wood or metal) of your railing - creating a stable and strong rail to hold accessories like planter rings, planter box brackets, shelves and hooks to hang plant baskets or tools.  Inventory is here!   Free Shipping on orders over $75, just $10 for anything less in the continental U.S.
