Gyms, weightrooms and climbing facilities all across the USA (and in 21 countries) use Spider Chalk Mega Blocks and they are now the standard for any weightlifter, powerlifter, gymnast or rock climber. We do not use fillers, binders or drying agents. Our manufacturing process produces a denser, cleaner and more pure block.
8 oz Mega Block Dimensions:
Weight: ~225 Grams
2x 8oz Blocks Per Box = 1lb Chalk
5.3 oz Mega Block Dimensions:
Weight: ~150 Grams
3x 5.3oz Blocks Per Box = 1lb Chalk
2. More Dense - Our manufacturing process makes the blocks less brittle so they don't break into pieces and make a mess.
3. More Chalk - Spider Chalk Mega Blocks are 225 grams or 150 grams per block, 3x the density of standard blocks.
4. Pure Chalk - Other blocks use binders which turns slimy when you sweat. We use only magnesium carbonate.
5. Made in the USA - All conventional 2 oz blocks are made in the same factory and private labeled. We are the only chalk company who manufactures blocks in the USA and we're proud to make Mega Blocks at our facility in Atlanta, GA.
