Abstract
A jack assembly for adjusting the height of a trailer is provided. The jack assembly is moveable between an operable and a stowed position. The assembly includes a tube having a slot portion and a slide block moveable within the slot portion. A post connected to the slide block protrudes through an opening in the slot portion to engage a clamping mechanism. The clamping mechanism is movable between a clamped position where the slide block is clamped to the tube to prevent the jack from moving, and an unclamped position where the slide block is movable within the slot portion to allow the jack assembly to be moved between an operable position and a stowed position.
