Adjustable Door Jamb Stop

Secured directly to the door jamb, these acoustical gaskets feature our unique Compress-O-Matic™ design with a sound-absorbing neoprene bulb that compresses to form a tight seal as the door is closed.

Both models include adjusting screws for field correction of irregular clearances that might compromise actual sound performance.

When used with a metal cased-opening frame, the #770 offers the added benefit of eliminating the need for an additional frame stop–and its unaesthetic projection into the door opening.

The gasket is also listed for use with both wood and metal acoustical doors with fire listings ranging from 20 to 90 minutes under both negative a positive-pressure testing standard. It is exceptional engineering, design features, and performance have made the #770 our long-time favorite for acoustical engineers and specifier.
