Water runs down the bar and into the bottom piece. Screw completely rusted through. Filled with rust and needs to be replaced. 5-years old. Very expensive for only a few years use--and can't buy just a new end piece.

Do not buy this item. After 4 years of use, my slide bar is completely unusable due to rust. The side bar is just falling apart. Now I need to buy another one to replace item. Don't make the same mistake.
