Collar-Mount Double Wall No Lid/Fill Sump

The octagon-shaped Collar Mount Double Wall Tank Sump is ideally configured for piping laid out in 45- and 90-degree angles. It comes without a lid for use with 3rd party multiport manholes. There is a v-groove pour channel to join the two-piece containment sump eliminating the need for lamination. The pour channel allows communication between the base and the top-hat. The base of the sump can mount to most industry standard 42- and 48-inch double wall collars. When used in conjunction with a Bravo fill sump multiport cover, it can be used as a fill sump.​
