RAILBLAZA C-Tug R Conversion Kit, 20 Inch, Set of 2

If you already run a C-Tug cart to haul your kayak down to the water, the RAILBLAZA C-Tug R Conversion Kit is how you bring it into the rail-base system. It's a set of two black rail bases plus all the stainless hardware you need, built to fit the Classic C-Tug, the Kiwi, and the Sandtrakz wheel cart. One kit, and your existing cart gets a cleaner, more repeatable way to mount up.

Here's the short version of why that matters. A standard cart leans on straps and a cradle to hold your hull. That works, but it can shift on you, and it takes a minute to get seated right every single time. The rail bases give you a fixed foundation to bolt to instead. Once they're set, the cart lines up the same way every trip. No fiddling on the beach while the tide comes in.

The bases are molded from UV-stabilized ABS plastic. That UV part isn't marketing filler. Kayak carts live in the sun, in the salt, and in the bed of a truck. Ordinary plastic goes chalky and brittle after a season or two of that. UV-stabilized ABS holds its color and its strength a lot longer. The hardware in the box is stainless steel, so it won't rust up on you the way plated bolts do around salt water. RAILBLAZA also uses acetal and polypropylene for the wear parts, both of which shrug off moisture.

Each kit gives you two C-Tug R rail bases, four green D-washers, four hex bolts, and four nylock nuts. The nylock nuts are the ones with the nylon insert, so they stay put under the constant vibration of dragging a loaded cart over gravel and sand. That's the kind of detail that keeps a mount from working itself loose halfway through the season.

Fitment is the one thing to get right before you order. This kit is made for the Classic C-Tug, Kiwi, and Sandtrakz carts specifically, and the rail bases run 20 inches. Measure your cart and your mounting spacing before you drill anything. If your spacing doesn't line up with the 20-inch length, stop and check the model before you commit. Getting that squared away up front saves you a lot of grief later.

Install is straightforward if you take your time. Mark your holes, drill clean, and seat the bases flat so they don't rock. Snug the hex bolts down evenly and don't overdo it. UV-stabilized ABS is tough, but any rigid plastic can crack if you crank a bolt well past where it needs to be. And if you're mounting on a cart or boat that sees salt water, a dab of anti-seize on the stainless threads is cheap insurance and makes the next teardown painless.

Who's this for? Anyone already invested in a C-Tug, Kiwi, or Sandtrakz cart who wants a solid, bolt-down mount instead of relying on straps alone. Beach launchers, surf paddlers, and anyone dragging a heavy fishing kayak across a long parking lot will feel the difference in how steady the cart tracks. When the cart isn't fighting you at the ramp, you spend less energy on the walk and more on the water. It's a small upgrade that punches above its price, and because it uses the same rail-base approach RAILBLAZA builds the rest of their gear around, it fits right into a setup you can keep adding to over time.

What it's not: it's not a complete cart, and it's not a set of wheels. It's the conversion hardware, the two rail bases and the fasteners. You'll need your existing compatible cart to use it. If you don't have one yet, grab the cart first, then add this to lock it into the rail system.
