Kneeboard Rack for Boat: The Kneeboard Rack for Boat is a great product that allows you to store your kneeboards securely on your boat. The rack fits clamp tubing sizes 1 3/4", 1 7/8", 2", 2 1/4", 2 3/8", 2 1/2", and is made of durable aluminum that will last for years to come. One thing I really like about this rack is its adjustable design, which allows you to customize the height and angle of your kneeboards to suit your needs. This makes it easy to access them when you're ready to hit the water, and ensures they stay in place even during rough seas. Another great feature of this rack is its compact size, which means it won't take up too much space on your boat. This is especially important if you have a smaller boat or if you want to keep other gear organized as well. Overall, I would highly recommend the Kneeboard Rack for Boat to anyone who wants to store their kneeboards securely and efficiently on their boat.
