The CH-1 Chalk Holder measures 40” high, making it the perfect fit your gym. Athletes will be more likely to use the chalk to enhance their performance if the bowl is elevated instead of sitting on the floor. Simple changes make the experience of working out smoother and more enjoyable. Purchase includes 1 box of Valor Fitness CH-2 Gym Chalk which contains 8 blocks of 2 oz chalk bricks, each measuring 3.5” x 3.5” x 1.75”. Made of magnesium carbonate, CH-2 Gym Chalk can also be purchased separately on its own if additional boxes are needed.
