Pemko 335AR Heavy Duty Interlock Perimeter Gasketing Set, One Header and Two Legs, Mill Finish Aluminum

The Pemko 335AR Heavy Duty Interlock Perimeter Gasketing Set delivers reliable weather and sound sealing for demanding commercial door openings. Designed as a complete perimeter kit, it includes one header and two jamb legs that interlock with the door edge to form a tight, continuous seal against air, dust, and drafts. Constructed from durable mill finish aluminum, the 335AR stands up to heavy daily use while maintaining consistent contact and performance. Its interlocking design provides a more secure fit than standard surface-applied gasketing, making it a strong choice for entrances, interior openings, and applications where energy efficiency and draft control matter most.

Features

• Complete perimeter set with one header and two legs for full door frame coverage.
• Interlock design engages the door edge for a tighter, more durable seal.
• Heavy duty construction built to withstand high-traffic commercial use.
• Mill finish aluminum offers corrosion resistance and long service life.
• Helps reduce air infiltration and improve door opening energy efficiency.

Functional Details

The 335AR uses an interlocking profile that mates with a corresponding element on the door edge, creating a continuous mechanical seal around the perimeter when the door is closed. This interlock action resists air and light infiltration more effectively than compression-only gasketing.

Included Components

This set is supplied as one header piece and two matching jamb legs, providing complete three-sided perimeter gasketing for a single door opening.
