Rail Risers were introduced by pontoon boat manufacturers in 2000. For years boat manufacturers built pontoons by bolting the fencing/rails directly to the carpet and decking. Direct mounting caused standing/pooling of water, because there was no were for the water to drain. This created moisture, mold and mildew and that results in rotting. Rail Risers allow you pontoon to circulate air and promote water drainage which lets your boat dry faster, helping to eliminate mold and mildew that cause rotting. See home page for video! Pricing is for a package of 32 rail risers.
Pick your size, they come in 3/8" and 1/2".
