This white bracket holds two 2 X 10 canister. This bracket is made from aluminum. This is the same bracket used on our AquaFX Dolphin
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 4 inches in diameter by 10inches in height, this is the size of the canisters used on most residential systems.
