R-Plus Standard Vertical Lift Doors for Cold Storage
R-Plus Standard Sectional Lift Doors come in both manual and electric models. Standard lift doors are available in sizes up to 12 feet tall and 12 feet wide, consult the factory for larger sizes. These doors are used on loading docks, aisle ways, obstructed areas, or wherever directional side clearance and ceiling height are limited.
