Pemko 2891AS Heavy Duty Perimeter Gasketing Kit — Mill Aluminum with Silicone Insert, 3'0 x 7'0 Opening
The Pemko 2891AS is a screw-applied, heavy-duty perimeter gasketing kit engineered to seal a standard 3'0 x 7'0 door opening. Also referenced as a door perimeter seal kit or door gasket set, the 2891AS ships as a complete head-and-two-jamb package — 17 linear feet total — so installers have everything needed to seal an entire door frame in a single order. The retainer profile measures 1/4 in. x 1-1/2 in. and is fabricated from mill aluminum, providing a corrosion-resistant, structurally rigid housing. A co-extruded silicone insert delivers the compressible sealing action, conforming to frame and door-face irregularities while maintaining a durable, long-lasting compression set.
Institutional Grade Features & Benefits
- Complete Perimeter Kit: Includes head and two jamb sections totaling 17 ft — covers a full 3'0 x 7'0 opening with no additional material required.
- Heavy-Duty Mill Aluminum Retainer: The 1/4 in. x 1-1/2 in. extruded mill aluminum housing resists corrosion, warping, and mechanical damage in demanding environments.
- Silicone Insert Sealing: The silicone compression insert provides superior resistance to temperature extremes, UV exposure, and repeated door cycles, maintaining an effective seal over years of service.
- Screw-Applied Installation: Fastens directly to the door frame with standard screws — no adhesive required — allowing for precise alignment, secure attachment, and straightforward field adjustment or replacement.
- Air, Sound, and Light Infiltration Control: Continuous perimeter contact reduces drafts, dust, and light gaps around the door slab, improving comfort and building envelope performance.
- Versatile Frame Compatibility: Mill aluminum finish integrates cleanly with aluminum storefront frames, hollow metal frames, and painted steel frames commonly found in commercial and institutional construction.
