Why aluminum

• Rust resistant: aluminum forms an oxide layer that resists structural rust, ideal for wet climates and open truck beds.
• Lightweight: about one third the weight of steel.
• Low profile: 0.5 inches tall keeps gear tight to the wall or rack.
• Side-mount option: keeps benchtop workspace clear on partition walls and carts.

Frequently Asked Questions

What weight can it hold?
37.5 lb on a wall mount and 75 lb on a floor mount. Ratings assume appropriate hardware installed into a suitable structure.

Is this a physical product or a digital download?
This listing is the finished, physical aluminum plate. It arrives deburred, cleaned and ready to install. If you would rather cut your own, see the DXF cut files.

What are the benefits of aluminum over steel?
Aluminum naturally resists rust, which suits wet climates and open truck beds where uncoated steel will corrode.

Does it fit full-width rolling chests?
No. It is made for half-width modular accessories and organizers.

Is mounting hardware included?
No. Mounting surfaces vary, so choosing the correct hardware for the installation is up to the end user or installer.

Do you make custom mounts?
Yes. If you need a different hole pattern or size, contact us with your requirements.

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

• 1/8" aluminum (0.125"): light and rust resistant.
• 11-gauge 304 stainless (0.125"): rust resistant without paint, made to order.

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.
