FREQUENTLY ASKED QUESTIONS
Is this a physical mount or a digital DXF file?
This listing is for the finished, physical metal mounting plate. It arrives at your door deburred, prepped, and ready for your fabrication or installation project.
Can I wall-mount this using standard screws?
For standard wall mounting where you need front-facing screws, we highly recommend checking out our Standard 14-Gauge Single Mount instead. This version is intentionally designed for bottom-up hidden fastening.
Does it come painted or coated?
It ships in raw steel, making it ideal for fabricators who want to weld it directly to a chassis or powder coat it to match a specific custom vehicle theme.
Sleek Profile for Low-Clearance Modular Builds
The Milwaukee Packout undermount is engineered for users who want a clean, minimalist layout without sacrificing security. By positioning the fasteners beneath the base plate, this mount keeps your modular storage flush and closely tracked to the vehicle framework. It's an ideal choice for motorcycle setups, overlanding rigs, and compact workspaces where every fraction of an inch matters. The durable steel build helps minimize rattling and movement, keeping your storage setup steady even on demanding terrain.
Heavy-Duty Performance Outlasts Standard Plastic Options
When it comes to high-vibration applications, standard plastic mounting brackets can crack or flex under heavy loads. This Milwaukee Packout undermount offers a reliable steel upgrade that stands up to severe daily use. The precision laser-cut lines align seamlessly with your tool boxes and organizers, providing a predictable latch every time. For custom builders and fabricators, having a stable steel foundation means you can count on your mounting gear to last through years of hard wear.
Versatile Design Options for Custom Racks and Vans
Beyond its strength, this Milwaukee Packout undermount simplifies custom shop and vehicle layout projects. Because it ships in raw steel, it integrates beautifully into welding projects, custom slide-out trays, or tailored motorcycle tail racks. It helps tradespeople and enthusiasts alike save time during installation by offering a flat top profile that avoids bolt head interference. It's a useful addition for anyone seeking an efficient way to mount modular components securely while keeping a professional, streamlined aesthetic.
10-Gauge Steel (0.1345" | Thickness of Two Stacked Dimes)
- Best For: Heavy-duty commercial wall mounts, shop workbenches, and massive modular tool stacks.
- The Advantage: Extreme structural stiffness. This ultra-thick steel completely eliminates flexing, twisting, and tool rattling, making it the definitive choice for demanding daily job-site use.
12-Gauge Steel (0.1046" | Thickness of a Standard House Key)
- Best For: Mobile service vans, enclosed trailers, and standard shop organization layouts.
- The Advantage: The ultimate sweet spot between bulletproof strength and smart weight distribution. It handles constant over-the-road vibrations flawlessly without adding unnecessary bulk to your mobile rig.
14-Gauge Steel (0.0747" | Thickness of a Nickel)
- Best For: Handheld battery organizers, small tool holsters, and lightweight shelf accessories.

What is Proposition 65?
Proposition 65 (officially known as the Safe Drinking Water and Toxic Enforcement Act of 1986) is a California law that requires businesses to provide a warning to California consumers if their products contain chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm.
These warnings are required even if the chemical is present in incredibly low amounts that may not pose any significant risk to your health.
