Weld-On Milwaukee Packout Half-Width Mount – Raw Steel, 10 or 14 Gauge

A raw steel weld-on base for Milwaukee® PACKOUT™ half-width (single) boxes and organizers. Laser-cut in Apple Valley, California, deburred and ready for MIG or TIG welding with no grinding prep. It is made for permanent installs on roll cages, service truck bodies, custom off-road racks, motorcycle tail racks, UTV consoles and shop pillars.

Where it mounts: welded to metal carts, bumper frames, roll cages and truck bodies.

Fabrication notes

1. Position the raw plate on your cart, bumper frame or roll cage.
2. Tack weld the corners and check alignment with a half-width box.
3. Complete your welds, let the metal cool fully, then click your storage containers into position.

Why a weld-on mount

• No fastener flex: welding to a metal chassis removes fasteners from the equation in high-vibration setups.
• Notched corners: corner reliefs are made for half-width modular organizers, for a tight, rattle-free seat.
• Pick your thickness: 10-gauge for extreme impact environments or 14-gauge for lighter, streamlined builds.

Frequently Asked Questions

Can I bolt this to a wall?
No. It is a flat weld-on base with no mounting holes. For bolt-on installs, choose one of our bolt-on half-width plates.

Will the raw steel rust?
Yes. Uncoated steel oxidizes over time if left untreated, so we recommend painting, clear-coating or powder-coating it after welding.

What is included?
The raw steel plate only. Toolboxes and welding consumables are not included.

Is this a physical product or a digital download?
This listing is the finished physical steel plate. If you would rather cut your own, see the Weld-On Half-Width DXF or browse all DXF cut files.

How long until it ships?
In-stock items ship within 1–2 business days. Made-to-order items ship in 1–2 weeks.

We fabricate our mounting solutions and accessories from mild steel, aluminum, and 304 stainless steel, built for harsh job-site environments. Choose the right finish for your build and review our care recommendations below.

Uncoated Steel (Paint Ready)

• Overview: Shipped bare and untreated, straight from fabrication. Ideal for custom painting, powder coating, or welding into custom racks.
• Appearance: May show light mill scale, surface scuffs, or minor flash rust on delivery, which is normal for uncoated steel.
• Care & Maintenance: Uncoated steel will rust when exposed to moisture, humidity, or air. We strongly recommend cleaning and lightly sanding the surface, then applying paint, clear coat, or powder coat before installation.

Powder Coated

• Overview: A durable, baked-on powder coat finish that protects the steel against wear, corrosion, and UV exposure. Powder coat is made to order.
• Appearance: A smooth, uniform finish, textured black on most plates and red on select Packout plates, ready to install out of the box.
• Care & Maintenance: Clean with warm water, mild dish soap, and a soft microfiber cloth. Avoid solvents such as acetone or paint thinner, and avoid abrasive scrubbers, which can wear the coating. Touch up deep gouges or scratches promptly to protect the metal underneath.

Uncoated Aluminum

• Overview: A lightweight, naturally rust-resistant option, about one third the weight of steel. Ideal for open truck beds, work vans, and marine or wet environments.
• Appearance: Bare metal with a clean industrial look. Aluminum forms a thin protective oxide layer on its own. Light surface grain or manufacturing tool marks may be present.
• Care & Maintenance: Wash with automotive soap and water. Aluminum may dull or develop a light oxidation over time, which is normal. To restore the shine, use a standard aluminum polish.

Uncoated 304 Stainless Steel

• Overview: Strong and highly rust resistant, for exposed truck beds, marine use, and wet or corrosive environments. Available on select plates, made to order.
• Appearance: A clean, bare metal finish that needs no paint or coating.
• Care & Maintenance: Low maintenance. Clean with soapy water or a stainless steel cleaner to remove grease, road grime, and fingerprints. Avoid steel wool and chlorine-based cleaners, which can mark or pit the surface.

What is Proposition 65?

Proposition 65 (officially the Safe Drinking Water and Toxic Enforcement Act of 1986) is a California law. It requires businesses to warn California consumers if a product can expose them to chemicals that the State of California lists as causing cancer, birth defects, or other reproductive harm.

These warnings are required even when a chemical is present in very small amounts that may not pose a significant health risk.

California Proposition 65 Warning

⚠️ WARNING: Cancer and Reproductive Harm. Products sold on this website can expose you to chemicals including lead, nickel, chromium (hexavalent compounds), titanium dioxide (airborne, unbound particles of respirable size), toluene, ethylbenzene, and formaldehyde, which are known to the State of California to cause cancer and birth defects or other reproductive harm. For more information, go to www.P65Warnings.ca.gov.

What our products are made from

Depending on the product, our items may include steel, aluminum, powder coat or paint (including spray paint), threadlocker, lithium grease, and plastics such as acrylic and acetal (Delrin). Metals and coatings can contain or release trace amounts of the chemicals above, especially during cutting, welding, sanding, or coating.

Why is this warning on my order?

BOCO Custom LLC ships products nationwide, so we include this warning to comply with California law. A Proposition 65 warning does not mean a product is unsafe or defective. It means a product may contain a trace amount of a listed chemical. We provide this information so you can make an informed purchase.
