The Clinton Floor Mounted Parallel Bars offer maximum flexibility for mounting where ever you wish as well as allowing you to decide the best distance between the opposing bars. Each upright has 6 inches of side-to-side adjustment and the bars can be mounted from 26 inches to 39 inches high. Height and width changes are made in 1 1/2 inch increments by pulling the spring loaded plungers and moving to the next hole. All hole locations are numbered to confirm that the bars are level and evenly adjusted. These bars are rated for 400 pound capacity. It is the buyer's responsibility to confirm that these bars are firmly attached to the floor with fasteners sufficient to restrain the intended load.
