Husky® offers Double Folding Frame Water Tanks for the end user that has limited storage space.  These unique frame tanks have a second folding point on the long side of the frame allowing you to fold the frame tank one more time cutting the overall length in half. Just pull the special heavy duty pins from the laser cut hinges and fold your tank again. The pins are secured to the frame to assure they will not be lost!

Husky folding frame tanks are available with the drain tubes mounted for inside or outside use. Standard tanks come with the drain tube mounted on the outside. If you would like your tank built with the drain tube on the inside, just let us know, and we will accommodate at no charge.

Husky® port-a-tank liners are designed with no bulky corners full of excess material that you don't need. Our patent-pending manufacturing process allows us to use one continuous piece of heavy duty 22 oz. vinyl for the side panel, which is then welded to our Husky® duty 28 oz. floor material. Combined with our patented "Easy Lift Handles" (US Patent No. 8,746,478 and other Patents Pending) welded to the liner floor, Husky's® frame tank liners are the most durable and easiest to use on the market today.

  • Available in NSF-61 approved (suitable for potable water)
  • Chemical and fuel resistant
  • Exclusive, patent pending, heavy duty floor increases the durability of the liner. With our heavy duty acrylic-coated 30 oz. floor material standard, Husky's® Folding Frame Tanks are the most durable on the market. Better than Hypalon!
  • Easy Lift Handles (US Patent No. 8,746,478 and other Patents Pending), offered only by Husky®, are mounted on the floor of our liners and make pick-up quick and easy
