The Pemko 305CN Standard Perimeter Gasket with Neoprene seals the gap between pairs of doors with a split astragal design. Because it mounts to the face of each door, it forms a tight seal that blocks smoke, fire, and air. As a result, it improves safety and helps reduce drafts in busy commercial spaces.

It features a clear anodized aluminum body and a flexible neoprene insert. When the doors close, the insert compresses to create a firm seal at the meeting stile. In addition, the screw-on design keeps it secure, while stainless steel fasteners add strength. Since each door needs its own piece, two units are required per pair.

Moreover, the 305CN is air infiltration tested, smoke tested, and fire rated. Therefore, it meets strict safety standards. At the same time, its simple design makes installation easy and ensures reliable daily use.

The Pemko 305CN Split Astragal with Neoprene Insert delivers dependable sealing performance for double door systems. Therefore, it is an excellent choice for commercial environments that require certified fire, smoke, and air control.
