Improving the seal around the header and jambs of active doors with a durable gasketing can reduce energy waste and save money on utility bills. A good seal also keeps out unwanted sound, dirt, insects, and light. Designed with your safety in mind, this door gasket is rated for excellence in halting fire, smoke, and air- infiltration.

Key Features Of This Product:

Ratings: This  door gasket is fire, smoke, and air- infiltration rated.

Casing Material: Has a strong, surface mounted, durable casing. Available in Bronze Mill Finish, Clear Anodized Aluminum, Dark Bronze Anodized Aluminum, Gold Anodized Aluminum.

Seals:  Available with a sponge EPDM or a sponge silicone seal. The firm seal  presses against the door when closed to completely seal the gap, which improves energy efficiency and halts infiltration of outside elements. 

Sponge EPDM is comparable to Sponge Neoprene, though it is more Eco Friendly and has better performance in many areas. Specifically, it has great sound control properties, is solvent resistant, and has outstanding heat and weather resistance.

Sponge Silicone Rubber has inherent resistance to harsh environments and temperatures. It does not become brittle and hard in the cold or very soft in the heat. This material has excellent resistance to sunlight, weather, ozone, oxidization, and water and to flame.

For more information on rubber seals, please see our Understanding Rubber Seals page.

Dimensions: Metal casing measures .875” in length and the seal extends .25” past the casing. Gasket can seal very slight gaps of .0625” or gaps as wide as .25”.

Easy Installation: Door Gasket is installed on the face of both doors.

A Note on Finishes: Bronze is a mill finish, sometimes referred to as Architectural Bronze. It is a solid bronze piece, which increases longevity and aesthetics, thus the large difference in price. It gets darker in color in time when exposed to the environment. Anodizing is an electrolytic process that applies a corrosion-resistant coating to the aluminum for longer wear and color maintenance. All Zero's anodized products are anodized to 204 (dipped four times)!


Installation instructions and screws provided. Screws are colored to blend unobtrusively with casing. Screw holes are slotted to allow for adjustments while installing.
