The 4-place double-sided poly kayak rack is constructed from recycled Eco-Friendly Poly Lumber that will never need to be stained, sanded, or painted again. Once your project is installed it is set for everyone’s enjoyment and years of low maintenance living, that won’t splinter, crack, chip, peel, or rot. It is built to handle the hardest conditions from hot sun and salt spray to heavy winds and even blizzards. The ultra-violet stabilizers protect the lumber so you can enjoy rich color for years to come. The Kayak rack comes disassembled but is very simple to put together with our illustrated assembly directions. We understand your commitment to the environment and sustainable living, and we strive to offer products that you feel good about using. Poly lumber is 100% plastic with no wood fillers to rot, peel, weather, or blister, and contains over 90% recycled HDPE plastic material. Common HDPE products are gallon style milk, water, and juice containers, as well as some detergent and shampoo bottles.
