I will try to use it for a bike rack in a pickup truck. It looks like it's doing what I wanted it to do. The only problem was that the coating was applied after the threads were cut and the threads had to be cleaned with a faucet.
Pros
EASY TO USE - Overhead line fittings install quickly. To reassemble: lift the end clamp and insert the two bottom washers into the slots. Slide it halfway between the two slots and release the clip to lock the L-rail bolts in the slots.
