A machine shop
that ships product

Rigid Hardware is the product arm of Rigid Concepts, LLC — a precision CNC machine shop in Van Alstyne, Texas. We hold tolerances to half a thousandth for customers who reject anything less, and we build products wherever we see good people wasting time on bad hardware.

The UBox started the way most shop products do: watching a builder field-fabricate an electrical box for a panel wall. Cut a hole, bend a patch panel, screw it on, apologize for it. Every barndominium needs dozens of them, every one is handmade, and every one looks it. So we machined the problem away — a patented, all-metal box and faceplate that mounts in the flat span between ribs and installs off a template in minutes.

Every UBox is machined, finished, and shipped from the same building in Van Alstyne. When you call about an order, you're talking to the shop that cut it.

Every UBox is inspected by a machinist before it's boxed. If it doesn't meet print, we replace it or refund it.

FAQ

The fine print, minus the fine print

Fit & construction
Which panel profiles does the UBox fit?
The UBox mounts in the flat span between the raised ribs of common steel wall panels. Send us your panel brand or profile — or a photo with a tape measure across one span — and we'll confirm fit before you order. The supplied template shows the required flat width.
What's included with each UBox?
The machined box body, the engraved faceplate in your chosen finish, mounting hardware, and the cut template. Add your wiring and devices and the opening is done.
Is the UBox UL listed?
Not yet — and we won't pretend otherwise. The UBox is engineered to UL 514A (the standard for metallic outlet boxes) and NEC Article 314, machined in a shop that works to print every day. Independent laboratory listing is planned as volume ramps. Requirements vary by jurisdiction, so check with your local inspector — and ask us for the spec sheet to show them.
What devices fit it?
Standard decora-style switches, receptacles, dimmers, and inserts — the same devices you'd buy at any supply house. The launch configuration is 2-gang; tell us which configurations you want next.
Ordering, finishes & returns
What finishes are available?
Anodized black, powder-coated white, and natural aluminum, all machined from the same billet stock. On volume orders we can run custom powder-coat colors to match your trim — ask before you order.
What tools do I need to install it?
A drill and whatever you already cut panel with. The template supplies the cut lines and screw locations, so there's no layout work.
Do you offer volume or builder pricing?
Yes. If you build barndominiums or wire them for a living, get in touch — volume pricing, custom colors, and scheduled releases so boxes show up when your rough-in does.
What's your return policy?
Unused UBoxes in original packaging can be returned within 30 days. Everything we ship carries our workmanship guarantee: if it doesn't meet print, we replace it or refund it.
