Jobsite-ready extension cords for construction, concrete, and trade professionals.

Shop heavy-duty extension cords built for construction jobsites, contractor use, and demanding work environments. Supply Haus stocks jobsite-rated indoor and outdoor extension cords designed to deliver reliable power for tools, lighting, and temporary power setups.

Our extension cords feature heavy-gauge wire, durable SJTW jackets, and molded plug ends to withstand daily abuse, weather exposure, and long runs without excessive voltage drop. Available in multiple lengths and configurations, these cords are ideal for framing, concrete work, remodeling, and temporary power distribution.

Whether you need an outdoor-rated extension cord for wet conditions or a heavy-duty cord for high-draw tools, these are the cords contractors trust to keep jobs moving without downtime.

Why We're Here

Built on one simple truth:

Contractors, the humans, deserve better than big-box "BS", overpriced catalogs, no site experience and promises that fall apart before lunch.

We built Supply Haus for the Hard Working Contractor who GSD (gets shit done), the operators, mud slingers, the framers, the pipe-fitters, electricians, carpenters, concrete crews, finishers, and job-site legends who actually keep this country erecting.

You know…the ones who show up early, stay late, bust ass, drink terrible gas-station coffee, solve problems with duct tape, and always figure it out.

1. Built, Not Bought.

Everything we make or source must survive real jobsite abuse.
If it doesn’t? It doesn’t make the cut.

2. The Culture Matters.

Construction isn’t just an industry.
It’s a language, a lifestyle, a brotherhood & sisterhood, a community!

We’re here to celebrate it, not sanitize it!

3. Gear That Makes You Laugh AND Last.

JIMI™ Gloves.
FNG™ Kits.
We take the work seriously, not ourselves!

4. Serve the Crew.

If it helps the crew, saves time, makes things safer, or reduces headaches… we stock it, bundle it, or build it, to serve our community.

This place is for you.

Sincerely,

The Average Joe
