Pemko 303DS Silicone Perimeter Door Seal Kit — Dark Bronze Anodized Aluminum, 3'0 x 7'0 Opening
The Pemko 303DS is a screw-applied perimeter door seal kit engineered for a standard 3'0 x 7'0 door opening. Each kit includes a head seal and two jamb seals, providing complete three-sided perimeter gasketing coverage totaling approximately 17 linear feet. The system combines a dark bronze anodized aluminum channel with a silicone compression insert, delivering a durable, weather-resistant seal around the full perimeter of the door frame. The dark bronze anodized finish coordinates cleanly with commercial and architectural hardware in matching dark bronze tones, making this a preferred choice for specification-grade door perimeter sealing projects.
Institutional Grade Features & Benefits
- Complete Perimeter Kit: Supplies head and both jambs in a single part number — no separate ordering of individual components required for a 3'0 x 7'0 opening.
- Silicone Compression Insert: Silicone gasket material maintains flexibility across a wide temperature range and resists compression set, ensuring lasting contact and consistent sealing performance over the door's service life.
- Screw-Applied Installation: The aluminum channel is fastened directly to the door stop or frame face, making installation straightforward for finish carpenters, door and hardware contractors, and facility maintenance teams alike.
- Dark Bronze Anodized Aluminum Channel: An anodized finish is integral to the aluminum — not a paint or powder coat — providing corrosion resistance and a refined architectural appearance that holds up in high-traffic commercial environments.
- 17-Foot Total Coverage: Pre-cut lengths sized for a standard 3'0 x 7'0 opening reduce field measuring and cutting time on the job site.
- Pemko Quality: Pemko is a recognized industry leader in door perimeter sealing, thresholds, and gasketing systems, widely specified for commercial, institutional, and governmental construction projects.
Applications
The Pemko 303DS perimeter door seal kit is well suited for commercial, institutional, and multi-family residential door openings where a complete, ready-to-install screw-applied gasket system is required. It is appropriate for exterior and interior door frames where control of air infiltration, dust, light, or sound transmission around the door perimeter is a priority. The dark bronze anodized finish suits applications where hardware and frame finishes are coordinated to match US10B / 313AN dark bronze specifications.
