Don't hit the road without securing your trailer properly! This Roadmaster Hitch Pin is the simple, reliable solution for keeping your hitch and trailer ball mount locked together. It's made for standard 2-inch receivers, which covers a huge range of trailers, cargo carriers, bike racks, and other towing accessories. The package includes one solid pin and a handy clip (also called an R-clip or linch pin) that slides through the hole to keep everything from bouncing out on rough roads. It's built tough from sturdy steel to handle the weight and stress of towing. Installation is a total no-brainer – just slide the pin through the aligned holes in your receiver and mount, then pop the clip in place. The pin itself is about 2.54 cm by 15.24 cm by 22.86 cm in the package and weighs around 0.272 kg, so it's substantial but easy to store in your glove box or tool kit. A must-have basic for any truck or SUV owner who tows. Keep your load safe and give yourself peace of mind on every trip!
