KEEP THE ENTRY SECURED
The door can remain closed and secured with a separate functioning deadbolt.

NO NEW HOLE THROUGH YOUR HOME.

Uses the standard 2-1/8” opening already in a compatible door.

The dangerous workaround

A cracked door or window should not be the price of bringing power inside.

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.

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.

Rain and Weather Intrusion

Gaps around a cracked door or foam-filled window can admit rainwater, hot and cold drafts, snow, and pests.

An Unsecured Entry Point

A propped-open door or removable window insert does not restore the security of a fully closed and latched entry.

Generator Exhaust

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

A tenant needed a better way to bring power inside.

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

From door knob opening to closed-door cord passage.

StormPlug™ is designed for setup before severe weather arrives. Final fit and performance specifications remain subject to final product validation.

Load the Inner Core

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.

Insert, Close, and Secure

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.

Check Unused Passages

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

A weather-resistant passage for compatible generator cords.

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.

Tool-Free Reusable Installation

Inside and Outside Sleeves are designed to press together through the existing door opening without permanently modifying the home.

Dedicated Cord Channels

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.

Use the Cord Passages You Need

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.

Weather-Resistant Architecture

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

One cord-passage solution for outages year-round.

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.

Designed for closed-door cord routing through hurricane season, summer storms, winter weather, and high-wind outages.

Safety utility first

Built around the risks families actually face.

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.

20+ FTOperate generators outdoors at least 20 feet from homes and buildings, with exhaust directed away from windows, doors, and vents.
CO ALARMSInstall and maintain working carbon-monoxide alarms on every level and outside sleeping areas.
DEADBOLTA separate functioning deadbolt is required so the compatible exterior door can remain secured during use.

Prepare before the forecast turns

Stop improvising during emergencies.

StormPlug™ is moving through product development and validation. Prepare before the next storm—and follow the product journey toward launch.
