Our highest quality, sound control door gaskets with adjustable solid neoprene bulb seal. Adjusting Screws are tapped and drilled (not stripped) allowing it to be used as the door stop itself.

Dimensions: Retainer measures .914" x 1.25". Length is custom cut to size.

Adjustable: A heavy duty adjustable door gasketing is designed to give a consistent seal at all times. When clearance increases with natural shifting, all it takes is a few turns of a screwdriver to restore a proper seal. It has an adjustable range of .3 inches.

Seal: It is fitted with a high quality solid neoprene seal and a neoprene interior for added protection. Solid neoprene seal is water and weatherproof and remains flexible in extreme temperatures. It has strong compression properties and will retain its shape through many usages. 

(It is also available with INTUMET™ Fire Stop feature, see our Adjustable Neoprene Sealing System FS).

Mitered Edge Design: Due to the size of this casing, the edge can be mitered, which ensures a stronger seal over straight edges. Another great advantage is that this gasket can be applied as a door stop (and replace your stop molding) or onto an existing stop. We recommend using it as a door stop itself. As a door stop it will run along the length of your door frame to the bottom of your door and will be compatible with a Surface Mounted Automatic Door Bottom.

MITERED EDGE IMPORTANT NOTE: Mitered edge will only be provided if quantities and sizes purchased form a set, such as (1) 36" and (2) 84". If irregular quantities are purchased this may be provided as a straight edge.

Compliance: Fire Rated ULC10c, Smoke and Draft Control, Air Infiltration, Sound Rated. 20 min fire rating when applied as a stop, 180 min when applied to a stop, BHMA Certified.

Heavy Duty: This particular door gasket is one of our most popular products in high sound protection areas as in recording studios, hotels, etc. The stainless steel version is also used frequently in cleanrooms and sterile environments.

Strike Mounting Bracket: This product can be applied with a door closer or a strike plate when applied with our specialized Door Closer or Strike Plate Mounting Bracket.
