Highland Hoppers use state-of-the-art technology for low profile, secondarily
contained aboveground storage of liquid fuels, new and used oils, waste solvents
and antifreeze. Hoppers are available in nine convenient capacities to meet every
need. Built to UL-142 specifications, each Hopper consists of an inner tank, within
a second tub-like steel container, providing a minimum of 110% secondary containment.
