Features and Benefits
A rigid 12-sided sump base that can be used on a 42” UST collar, a manway, or a bung adapter. Smooth flat panels are easy to drill and provide leak-tight sealing surface for penetration fittings.
Adjustable Upper Body
A large adjustable top provides 28” of height adjustability to work in both shallow burial as well as deep burial applications, with only one simple field determined cut.
Two-Part Design with Epoxy Bonding Trough
Makes installations simpler than ever. Installers have plenty of room to install the equipment in the base before the upper body is attached. Then, one simple epoxy pour guarantees a watertight bond.
