Vertical Lift Doors
Vertical Lift Doors can be designed for storing the door panels in the raised position on either the interior side or the exterior side of the adjacent wall structure.
- Interior mounting the doors provides the most economical installation however, if ceiling height is insufficient for interior mounting, the door can be attached to the building’s exterior wall.
- Exterior mounted doors are designed with a weather hood structure that stores the door panels above the clear opening whenever the door is fully lifted.
