EASILY CHANGE WEIGHTS BETWEEN SETS. Our deadlift jack raises the inner most plate just enough to add or remove weight quickly and easily. No more struggling to change weights! WORKS WITH ALL WEIGHT PLATES. Our deadlift wedge is designed to work with all metal iron plates and bumper plates. Even hex and other oddly shaped weights can be used. FITS EASILY IN YOUR GYM BAG. Large metal deadlift jacks are very expensive and not portable, which won't work for a lifter who travels to a gym or is building a home gym on a budget.
