The Slater Slammer is a massive tire sledge designed to allow the athlete to pound on tractor tires or rubber blocks for the ultimate in conditioning. The weight of the Slammer is 22 lbs/10 Kg and is fillable with buck shot, bb's or sand. The Slammer fully loaded weighs 55 lbs/25 Kg. It features a 30.5" long, 1.9" wide handle topped by a round, 6.5" diameter steel bell. Unlike a regular sledge, it's designed so there is less of a chance of twisting the wrist.
