Swing-Up Sectional Post

• A perfect answer for openings that are too large for a single overhead door that must accommodate large machinery or equipment on an infrequent basis. Operating on a single pivot point that is designed to swing left or right, it allows the use of one (1) smaller door for everyday requirements and the full opening when needed

 

Pass Through Doors

• Whether it's for convenience or necessity, there are circumstances where a pass-through door is requested to provide ingress and egress in an overhead door enclosed opening without having to open the overhead door. Northeast Georgia Gutters and Garage Doors, Inc. can accommodate this need with a state-of-the-art design pass-door option. Available in urethane core models 3216 and 3212, it's the ideal choice to solve this need.

 

Header & Jamb Seals

• Seal the perimeter of the opening to provide additional air infiltration and thermal protection
