Vertical Lift Doors for Manufacturing
Vertical Lift doors for aviation 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. Two styles - inside mounted and outside mounted - are available in 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.
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 sash, personnel doors, insulation and louvers.
