Our unique ratchet tensioning device, dead axle design and pre-lubricated springs provide a door that's built to withstand the toughest workout. We also manufacturer a line of portable storage units called MASS (Movable Additional Storage Structures). MASS units are classified as equipment, which brings certain tax benefits and may eliminate the need for a building permit. MASS units have the look and usability of a storage unit, but can be used in a variety of applications.
