Column Followers
OVERVIEW
Column followers are a wind protection option used for steel building applications. The column followers are located at the bottom inside corners of the door and slide along the inside flange of the building columns or the self-supporting header. They prevent the bi-fold door from pushing out from the building when a significant positive air pressure is present inside.
The column follower pin is sleeved in a nylon bushing to reduce noise and provide a smooth quiet operation.
The column followers are installed to the steel frame in factory and are easily adjustable to accommodate different flange depths.
