Pemko 346C40 40" 3' 4" Door Top Weatherstrip Clear Anodized Aluminum Finish

The 346C40 door top weatherstrip mounts at the head of exterior doors to deflect rainwater and prevent moisture infiltration through the door-to-frame gap. This fire-rated aluminum strip installs on commercial and institutional buildings where water penetration causes interior damage, mold growth, and energy loss. Pemko engineered this projection strip to handle weather exposure while maintaining fire door assembly integrity.

The clear anodized aluminum construction resists corrosion and provides long-term durability in harsh weather conditions. The 40-inch length covers standard single door widths with minimal field cutting required. Mounting hardware comes included for direct attachment to the door frame head.
