Husky® Portable Containment's Aluminum Quick Assemble AQUA Tank gives you the best of both worlds—a rigid frame AND portability. The AQUA Tank snaps together quickly and fits into its own storage bag for easy handling and compact storage. The rigid top (AQUA Tank Type I only has top rail) and bottom rails give the strength for throwing hoses over the top, no hose stand needed. The frame pieces are built from 6061 aircraft quality aluminum tubing. The corners are a slip in fit (Aqua Tank II & III) which, after the liner is installed, allows the top and bottom rail pieces to lock into place. No pins or wires to fight with and NO TOOLS NEEDED! Easy set up—it's a snap!
