Pemko 5110BL120 Self Adhesive Astragal 120 in Black

Product Description

The PEMKO 5110BL120 is a self-adhesive astragal strip finished in black, designed to seal the gap between door panels at the meeting stile on double-door assemblies. At 120 inches (10 feet) in length, this astragal provides a continuous seal that helps control air infiltration, light gaps, and sound transmission. The pressure-sensitive adhesive backing simplifies installation without the need for mechanical fasteners, making it a practical solution for door openings that require a clean, finished appearance. It is typically installed by door hardware professionals, commercial glaziers, or experienced finish carpenters working on architectural door assemblies.

The 5110BL120 is suited for use on double-door or paired-door assemblies in both commercial and residential applications where a surface-applied astragal seal is preferred. Its 120-inch length accommodates standard and taller door heights commonly found in commercial construction. The black finish integrates cleanly with dark-finished door hardware and frames. This product is part of the broader PEMKO line of architectural door accessories, which includes weatherstripping, thresholds, door bottoms, and perimeter gasketing.

Installation Notes

Installation is typically performed by a door hardware professional or experienced finish carpenter. Before applying, ensure the door stile surface is clean, dry, and free of dust, oil, or old adhesive residue to achieve proper bond strength. No mechanical fasteners are required, but surface preparation is critical for long-term adhesion. Refer to applicable building codes and the door manufacturer's guidelines when installing astragals on fire-rated or smoke-labeled door assemblies.
