Larson / Pella Storm door sweep with Dual Fins to reduce air flow and help prevent leaves and other items from blowing under the storm door.
Double Vinyl Fin Sweep slides into Storm Door Expander

Application: Storm door bottom sweep
Door Size: Fits doors up to 36 inch
Length: 37 inches, cut to length
Color: Black

Note: This slides into the bottom of the metal expander on bottom of storm door. Cut to length as needed with razor knife or scissors. May be helpful to pinch the end to keep sweep from moving after installation.

Note 2: If difficult to slide vinyl into expander, use a little dish soap to lubricate. If vinyl is rigid, leave in a warm room till it softens or use a hair dryer.
