I was initially nervous as the tubes only slide onto the metal bars, with no fasteners to hold them on. I haven't had any issues with it after several trips to the lake. Having guide posts is SO nice, especially when putting the boat on the trailer with any wind. Keeps things aligned!
The U bolts were 1/2 inch short. The pvc uprights do not attach to the metal uprights they sit on. I am concerned they may come off when the trailer is backed into the water. I am also concerned about the metal pieces rusting when used around salt water.
Good product, good price. Directions were sparse but still an easy install. Makes recovery, especially with some wind so much easier. Not sure about durability but for the price, if it lasts 3 or 4 years, it’s worth it.
