Do you have larger rods for Catfish, Muskie or saltwater species that do not fit your traditional 30 in. rod storage rack. At Rush Creek Creations we are passionate about fishing and developed a solution for this problem, the 38 mm Black 6 in. Steel Extension Post. This is how it works. Most floor rod racks are a standard 30 in. H and are designed for standard freshwater rods. By adding the 6 in. extension post to any Rush Creek Creations rod storage rack with the 38 mm steel center post you elevate the height of the top of the rack. By doing so, the rod taper is slightly thinner and will accommodate the larger diameter rods. We also have a variety of rod storage racks that have the innovative Dual Rod Clips and when you add the 6 in. extension post you will be able to fit larger saltwater rods without an issue. Below is the list of Rush Creek Fishing Floor Storage Racks the extension post will be compatible with: Rush Creek Creation Bass 16 Round Rod Rack, REALTREE 16 Round Rod Rack, Rush Creek Creations Americana 16 Round Rod Rack, Rush Creek Creations Dark Walnut 16 Round Rod Rack, Rush Creek Creations Barn Wood 16 Round Rod Rack, Rush Creek Creations American Cherry 16 Round Rod Rack, Rush Creek Creations 24 Spinning Round Rod Rack, Rush Creek Creations Barn Wood 24 Spinning Rod Rack, Rush Creek Creations Dark Walnut 24 Spinning Rod Rack.
