Collar-Mount Double Wall

The octagon-shaped Collar Mount Double Wall Tank Sump is ideally configured for piping laid out in 45- and 90-degree angles. It comes standard with a snap-lock lid with imbedded O-ring seal to make it watertight. 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 be applied to most industry standard 42- and 48-inch double wall tank collars. Sumps can be monitored by Vacuum, Liquid, and Dri interstitial monitoring.  ​
