Husky® Folding Frame Tank Racks are stainless steel or aluminum, portable, and come with a manual release mechanism. These lightweight sturdy racks are designed for easy installation. On standard size racks, there are three hinged feet with four pre-drilled 3/8” holes per foot. This allows for easy mounting. There are two locking points, one on each end that will require two screws each. Installation can literally take only minutes.
