Wind Damper Function

The damper helps control the movement of compatible door panels and breakout assemblies.

A properly functioning damper can help:

This can be particularly important on commercial entrances exposed to wind or frequent pedestrian traffic.

Stanley automatic-door systems use different damper configurations depending on the door series, panel arrangement, and installation.

Always confirm that the existing opening requires the long retrofit damper configuration before ordering.
