The PCI CLS Series Tank Collar provides a rigid mounting foundation for tank sumps on underground storage tanks. Built from 100% corrosion-resistant fiberglass using closed-mold technology, the CLS combines consistent construction with features that simplify installation, shipping, and storage.

Available in a 42-inch model, the CLS features an integrated U-shaped epoxy trough, factory-cut tank fit, and a nestable design with stacking lugs.

Closed-Mold Construction

Closed-mold technology produces consistent wall thickness and smooth surfaces inside and out, helping deliver a precise fit and consistent installation.

Integrated U-Shaped Epoxy Trough

The integrated U-shaped trough receives epoxy to create a continuous, watertight bond between the collar and sump. This design simplifies bonding and supports dependable containment.

Factory-Cut for Tank Fit

Each collar is cut at the factory to match the specified tank diameter, reducing field variability and installation time.

100% Fiberglass Construction

Corrosion-resistant fiberglass provides long-term strength and a durable mounting foundation for underground containment applications.

Nestable Design with Stacking Lugs

Collars nest together for efficient shipping and storage. Integrated stacking lugs support organized stacking, helping reduce freight costs and warehouse space requirements.
