The Block and Roll Mover provides easy moving of up to 700lb tent ballast cement blocks. The black color of the Mover allows for ease of use with stage and film production. The Mover is made with structural aluminum and features heavy duty wheels. This innovative design allows 3 different size blocks to be moved with the least resistance. Our revolutionary fork pocket design ensures the block will not fall off while in motion. 500lb blocks are most common size and offer excellent versatility. Aluminum construction (steel axle), Professionally coated finish. Because our carts rely on body weight as counterbalance, not all users will be able to tip 500lb or 700lb blocks.
