ISR Rails, Capture Plates, and Accessories

What are ISR rails and capture plates used for?

ISR (Industry Standard Rail) systems are the under-bed mounting platform that connects a fifth-wheel or gooseneck hitch to the truck bed. The rails bolt to the frame, and the capture plates lock the hitch head into place so it can be removed when you need a clear bed. This collection covers 34 components including rails, capture plates, mounting brackets, and the small parts that wear out or get lost during hitch swaps.

How do I know which ISR rails fit my truck and hitch?

Fitment depends on three things: your truck make and bed length, the hitch brand and model (Reese, Pro Series, Husky, etc.), and whether you have a short-bed or long-bed configuration. Always confirm the hitch model number stamped on your existing head or rail before ordering. If you are pairing a new hitch with these rails, check the manufacturer's compatibility chart, or text/call us at 817-984-1852 and we will verify the match. You may also need required hardware for the RTX2000 depending on your setup.

Can I use ISR capture plates with any brand of fifth-wheel hitch?

ISR is the industry-standard rail spacing adopted by most major hitch manufacturers, so capture plates and rails are generally cross-compatible between brands like Reese, Pro Series, Husky, Draw-Tite, and Valley. The exception is older proprietary systems and some Curve Q-series hitches, which use a different mounting pattern. Match the capture plate to the hitch head, not the truck, and verify the base rail spacing is 22 inches center-to-center.

What other towing and hitch accessories should I look at?

If you tow with a fifth-wheel or gooseneck, it is worth checking your electrical connections and adapters at the same time. The RV plug adapters collection covers 7-pin to 4-pin conversions and shore power adapters. For outdoor setup at the campsite, the tailgate collection includes accessories that pair well with truck-camper rigs.

Do ISR rails ship free?

Orders over $100 ship free within the continental US. Heavier rail sets and full kits occasionally ship via truck freight, which is noted on the individual product page along with any freight charge. Smaller capture plates, pins, and hardware ship standard ground.
