The Collapsible Dumbbell rack is great for those on a budget. This rack holds 4 dumbbells as it is nice to have an extra training dumbbell in the field when working. The Dumbbell Rack is made from heavy 1” aluminum square tubing with the back brace out of 3/8” rod, and comes with 2 stakes to hold it into the ground. This dumbbell rack is budget friendly as it does not have the extra powder coated finish, and the back support is made out of 3/8” rod. This rack is still very stable and easily transportable. We have pilot holes drilled and a stake system so that the rack can be used indoors and outdoors easily. This also helps protect the interior of vehicles when transporting the rack. No tools required to set up. Dumbbells not Included.
