Astragal For Double Doors

Entry Systems AstraSeal Brush Aluminum Astragal Door Seal - For Hollow Metal Steel Door Pairs, Commercial Wood Door Pairs, Or Storefront Door Pairs - Seals Gap Between Center Of Doors

The Entry Systems AstraSeal™ Brush Astragal Door Seal is engineered specifically for commercial door pairs to eliminate the common center gap between doors. This heavy-duty astragal creates a tight, consistent seal to help block air infiltration, dust, debris, insects, and wind drafts—while maintaining performance in high-traffic commercial environments.

Commercial door pairs are widely used for rear exits, fire-rated openings, and service entrances in retail stores, office buildings, warehouses, schools, and hospitals. These openings often develop a visible gap between the two doors, which can lead to failed inspections, energy loss, and security concerns. The AstraSeal™ system is designed to solve that problem with a durable, commercial-grade sealing solution.

Built for 7'0" Commercial Door Pairs

Unlike residential-grade astragals that fail under heavy use, the AstraSeal™ Brush Astragal is built for commercial door applications. The reinforced aluminum holder securely retains the dense nylon brush, preventing pull-out or failure even in high-cycle door openings.

This makes it ideal for:

• Fire-rated commercial door pairs
• Back-of-house commercial exits
• Warehouse and service doors
• High-traffic retail and institutional openings

Seal the Center Gap - Improve Performance & Compliance

A gap between door leaves can allow unwanted air transfer, pest intrusion, and reduced building efficiency. The AstraSeal™ system installs directly to one door leaf and creates a continuous seal along the meeting stile, improving overall door performance.

This is especially important for:

• Maintaining proper building envelope sealing
• Reducing drafts and energy loss
• Improving door system reliability
• Helping meet fire door assembly requirements

Retrofit Friendly for Existing Door Pairs

The Entry Systems AstraSeal™ is designed for easy retrofit on existing commercial door pairs. It surface mounts to the face of the door and can be field-adjusted as needed.

In some applications, minor trimming of the aluminum holder may be required when:

• Lock hardware is installed close to the door edge
• Oversized cylindrical lock trim (large rose plates) is present
• Special door preps or hardware interfere with mounting location

The aluminum carrier can be easily cut in the field to ensure a proper fit around hardware while maintaining a continuous seal.
