The Hydra HPS-FOB Adjustable-Foldable A-Frame Brace comes standard with most Hydra steel wall pool kits. The Brace System comes with two components. The foldable brace and adjustable caster and the reinforcement stake. The brace must be installed on the bottom of a wall panel, then folded up and adjusted to fit to the top of the panel. After the brace is bolted in place, it can be staked in the ground using the reinforcement stake and a bolt/nut. This is a very effective bracing system and combines several pieces to provide a very simple and easy installation process.
