Profile: Easy-Rack offers freestanding Auto-Tilt, double stillage, stacker truck (hoist), and 3-tier bottle shelving. The manual stacker truck (hoist) is for lifting containers onto the double stillage. The Auto-Tilt freestanding unit holds 9-22 gallon containers with no adjustment needed for the different size container. At the front end of the Auto-Tilt there is an Allen stud which is used to alter the angle (tilt) because some beers carry more ullage than others, this will prevent ullage being drawn through the beer lines. The Auto-Tilt stillage is zinc plated to prevent corrosion.
