Joist Protector™ is a joist and pier cap system designed to protect and lengthen the life of your deck. Made from a recycled polyethylene material that provides a waterproof membrane. It works like an umbrella to keep the joists and undersides of the deck planks clean and dry. Joist Protector protects critical areas of joist and deck plank which liquid sealers never reach. This product eliminates the most common cause of deck failure, the rot migration between the joist and underside of the deck plank. It eliminates wood-to-wood contact.
To provide a cap over dimension lumber for decks, boats, patios, amphitheater, greenhouses, picnic tables, benches, pergolas, huts, bars, gazebos, bridges, and etc.
