Description
The 4000 Gallon Husky® Portable Steel Folding Frame Tank (MPN: STF-4000) is engineered for high-capacity liquid containment needs in emergency response, fire suppression, oil spill recovery, and industrial settings. Featuring an innovative folding frame and superior liner design, this tank delivers rapid setup, long-term durability, and unmatched field performance.
The liner is manufactured using a single continuous sidewall panel that is welded to the Husky®-Duty floor—eliminating bulky seams and sagging fabric. Choose from high-performance vinyl or EXLON® liners, each offering excellent UV, abrasion, chemical, and cold-crack resistance. Designed for easy transport, storage, and use, the tank includes patented Easy Lift Handles and dual 10" Quick-Release Drain Tubes to streamline draining and inter-tank connections.
