The SeaSucker Horizontal Rod Holder may not look like much, but this will hold six fishing rods! The other rod holders SeaSucker offers are vertical mount, but the horizontal mount might be preferrable for your truck bed or the inside of your boat. There is a 4.5 inch vacuum mount on each side. The rods are stored criss-cross for maximum storage, due to the rubber insert, finished with a velcro strap to keep the rods in place. So, wet your lines with the SeaSucker Horizontal Rod Holders!
