Jobsite-rated power adapters, GFCI protection, and spider boxes for safe temporary power distribution.

Jobsite power control and protection starts here. Shop adapters, GFCIs, and spider boxes built for construction, concrete, and temporary power applications where safety, durability, and reliability matter. Supply Haus stocks jobsite-rated power accessories designed to safely adapt, distribute, and protect electrical power on active worksites.

This collection includes heavy-duty power adapters, in-line and outlet-style GFCI protection, and spider boxes that allow multiple safe power drops from generators, temporary panels, and main feeds.Designed for demanding environments, these products help reduce electrical hazards, prevent nuisance trips, and keep power organized across busy jobsites.

Ideal for framing, concrete pours, remodeling projects, and temporary installations, these jobsite power solutions are essential for maintaining safe, efficient, and code-conscious power distribution wherever work is happening.

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
