This chrome bracket holds three 2 X 20 canisters. This bracket is made from aluminum.
Please keep in mind that our canisters are measured based on filter size. So while this bracket holds three of the 2 X 20 canisters, these canisters actually measure approximately 4 inches in diameter by 20 inches in height, this is the size of the canister used on our Blue Marlin, a commercial system.
