Pemko 357SP84 T Overlapping Astragal with Pile 84 in Galvanized

Product Description

The PEMKO 357SP84 is a T overlapping astragal with pile weatherstripping, finished in galvanized steel, designed to seal the gap between double doors at the meeting stile. It mounts to the inactive door leaf and creates a compression barrier against air, light, dust, and drafts. At 84 inches in length, this astragal covers a full standard door height. The galvanized steel construction provides corrosion resistance suitable for both interior and exterior applications. Installation is typically performed by commercial door hardware specialists, finish carpenters, or general contractors during door assembly or retrofit weathersealing projects.

This astragal is suited for commercial and residential double-door assemblies where the inactive leaf requires a surface-applied meeting stile seal. The T overlapping profile with pile insert is commonly used on wood, hollow metal, or composite door pairs in entryways, vestibules, and corridor openings where controlling air infiltration and light gaps is a priority. It is sold individually as a single unit and is field-cuttable to fit openings shorter than 84 inches.

Key Features

• T overlapping profile seals the meeting stile gap on double-door assemblies
• Pile insert provides a soft, compressible barrier against air and light infiltration
• Galvanized steel finish resists corrosion in interior and exterior environments
• 84-inch length covers standard full-height door openings
• Surface-applied mounting allows retrofit installation without door modification

Compatibility

Designed as an OEM-style surface-applied astragal for standard double-door assemblies requiring a T overlapping meeting stile seal.

Installation Notes

Installation is typically performed by a licensed door hardware installer or finish carpenter. Before installation, ensure both door leaves are properly hung, aligned, and adjusted. Secure the astragal to the inactive door leaf per the manufacturer fastening pattern, and verify that the pile seal compresses evenly across the full length of the meeting stile when the doors are closed. Field-cut to length as needed using metal shears or a miter saw equipped for steel profiles.
