Taco Marine’s award winning, newly patented Ratchet Hinge is designed to provide boaters the ability to easily adjust the sitting angles for sunpads, loungers, and many other types of boat seats. The ratchet hinge automatically locks securely into place every 15 degrees past the catch point, or is adjustable depending on the seating application. It’s easy to adjust, simply pull up on the seat back to engage the hinge – and it can be set to release automatically at 32, 64, or 98 degrees. Individual hinges have been tested for up to 600 ft. lbs of weight against the seat back.
