Ultra-Fab's Adjustable Ultra Footpads are the perfect solution to trailer sinking and tilting on soft surfaces. Made heavy duty steel, the outer pad edges won't bend even when struck repeatedly on hard surfaces. Their extra large 8" x 5" footprint spreads the trailer's weight proportionately. The adjustable footpads include vertical fine-tune. There is no need to carry cumbersome wood blocks when you have these heavy duty fixed footpads.
