Pinched or Damaged Cords
A door closed against heavy extension cords can compress, abrade, or damage their jackets and prevent the door from closing correctly.
Weather-resistant generator cord passage
Route up to three compatible generator extension cords indoors—without leaving a door or window cracked open.

The dangerous workaround
Running generator cords through a partially open door can pinch and damage the cords, while a pool noodle in a cracked window can leave gaps around them. Both workarounds expose the home to weather and create an unsecured entry point.
A door closed against heavy extension cords can compress, abrade, or damage their jackets and prevent the door from closing correctly.
Gaps around a cracked door or foam-filled window can admit rainwater, hot and cold drafts, snow, and pests.
A propped-open door or removable window insert does not restore the security of a fully closed and latched entry.
Open doors and windows near generator operation can provide a path for dangerous carbon monoxide. Proper generator placement and working CO alarms remain essential.
Born from a real Kingwood power-outage problem
Frequent outages in Kingwood, Texas made a portable generator a practical necessity. A tenant routed generator cords through a partially open bedroom window using a pool noodle, but rainwater on the carpet and an accessible window remained real concerns. The experience revealed a broader need shared by families who otherwise pinch cords through cracked doors.
Six simple steps
StormPlug™ is designed for setup before severe weather arrives. Final fit and performance specifications remain subject to final product validation.
1
Remove the door knob or handle and latch assembly. Keep the original hardware together for reinstallation.
2
Insert the Inside and Outside Sleeves through the existing 2-1/8-inch door knob hole. Align the arrows at the top and press the sleeves together.
3
Route your compatible outdoor-rated extension cords through the open sleeve tunnel.
4
The plugs ship installed. Remove plugs only from passages needed for cords. From inside the home, press each cord sideways into the Inner Core C-slits, with the 10-gauge passage at the bottom.
5
From inside the home, push the loaded Inner Core straight into the sleeve tunnel until fully seated. Close the door and secure it with the separate functioning deadbolt.
6
From outside the home, confirm that every unused Inner Core passage has its matching plug securely seated. Leave unused passages plugged.

Designed for simplicity, compatibility, and reuse
StormPlug™ is being developed for a standard 2-1/8-inch door knob opening in a compatible 1-3/4-inch-thick exterior door. A separate functioning deadbolt is required for door installations.
Inside and Outside Sleeves are designed to press together through the existing door opening without permanently modifying the home.
The flexible Inner Core uses dedicated channels designed for one compatible 10-gauge cord and up to two compatible 12- or 14-gauge outdoor-rated extension cords.
Three removable plugs ship installed in the Inner Core. Remove only the plugs needed for compatible cords and leave unused passages plugged. Two small plugs fit the 12-/14-gauge passages; one large plug fits the 10-gauge passage.
The sleeve-and-core design is intended to help reduce open gaps around compatible cords and limit drafts, wind-driven rain, and pest intrusion. Performance claims remain subject to final validation.
Prepared through every season
Severe weather looks different across the country. StormPlug™ is designed to help keep compatible generator cords routed through a closed exterior door during outages caused by hurricane rain, thunderstorms, winter weather, and damaging winds.
Safety utility first
StormPlug™ is a weather-resistant cord-routing product. It is not a carbon-monoxide barrier and does not replace safe generator placement, manufacturer instructions, or working CO alarms.
Prepare before the forecast turns
StormPlug™ is moving through product development and validation. Prepare before the next storm—and follow the product journey toward launch.
