Vertical Lift Doors
Vertical Lift doors for aviation and industry are preferred by people in production and maintenance - the people who know. Fleming doors withstand the most severe punishment and are fast with dependable operation that lowers costs and increases production efficiency. Perfect counterbalance gives every Vertical Lift door a safe and smooth operation with either the manual operator, or the motor operator which lifts the door at (minimum) 45 vertical feet per minute. Special installation features include gravity safety dogs, windows, translucent panels, personnel doors, insulation, louvers, and many other special requirements.
Two styles - inside mounted and outside mounted - are available in single or multiple sections to fit available headroom. Where inside headroom is limited, the Outside Mounted type is ideal, requiring no alterations to existing framing, power and piping lines or fixed equipment.
