Motorcycle Mount for Milwaukee Packout Full Width Boxes (Center Only Mount) Universal Fit

A center-only mount for Milwaukee® PACKOUT™ full-width boxes and coolers. It secures your gear using only the center two rows of feet, so you do not need the full footprint of a standard base. It is made for motorcycle racks, scooters, narrow shelves, ATV trays, UTV beds and compact truck beds, in 14-gauge steel or 1/8-inch aluminum. Laser-cut in Apple Valley, California.

This mount is used on moving vehicles, where vibration and road shock add to the load. The recommended maximum is a conservative guide, not a rating. Always stay within your motorcycle's and rack's load limits, and use hardware and mounting points suited to the vehicle.

Where it mounts: motorcycle and scooter racks, ADV and dual-sport bikes, ATV and UTV beds, and narrow shelves.

Why a center-only mount

• Less bulk: it drops the side rails of a standard base to cut weight and keep your gear centered over the rack.
• Less side-to-side shifting: the streamlined profile helps on trails and highway commutes.
• Snap fit: the center-cleat design gives a click-and-go fit that keeps plastic modular cases from rattling on rough terrain.
• Steel or aluminum: choose aluminum when weight matters.

Frequently Asked Questions

How much weight can I put on it?
We recommend keeping the box and its contents to 50 lb or less, and never exceeding your motorcycle's or rack's own limit. Because this mount rides on a moving vehicle, we do not publish a wall or floor rating for it.

Will the uncoated steel rust?
Uncoated steel is susceptible to surface oxidation, so we recommend painting or coating it. Powder coat and aluminum options are available.

Can I weld it?
Yes. The uncoated steel version is weld ready.

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.

• 14-gauge steel (0.075"): light duty. Lighter gear and accessory mounts.
• 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.
