This Solid Aluminum bracket holds two 2 X 10 canisters. This bracket is made from NEVER RUST solid Aluminum .
Please keep in mind that our canisters are measured based on filter size. So while this bracket holds two of the 2 X 10 canisters, these canisters actually measure approximately more than 2 inches in diameter by 10 inches in height, this is the size of the canister used on our Residential Systems
