The Tank Check Tank Anchor is a folding tank stand that attaches to the base of your tank, a great alternative to those bulky and tall tank stands found in most stores. It protects your car and floor surfaces from the rust and grime that can build up on cylinders, and folds up nicely for storage when not in use. The Tank Anchor can also be used in conjunction with a standard tank sensor, providing space for the sensor as well as improved wireless range. A nice alternative when replacing lost aluminum spacers. With or without a sensor, the Anchor is a great accessory for any propane cylinder user.
