Review on 🚐 RV Designer A101, White Nylon Two Wheel Carrier - Pack of 14, I Beam Track Compatible, Window Covering Hardware by David Foster

Perfect replacement for the broken curtains on my boat. One didn't turn well, but there was more in the pack than I needed, so that's not a problem. They DO NOT slide apart for installation, they are meant to be mounted on a rail at the end of the rail, there is usually a screw that needs to be unscrewed, and then they slide straight onto the rail. If you try to pull them apart to put them on the rail it won't work and they will just break.
