How to Mount Milwaukee PACKOUT in a Van (Two Approaches That Actually Hold)

Mounting Milwaukee PACKOUT in a van comes down to two real options. Option 1: bolt a PACKOUT mounting plate through the van floor — permanent, zero movement, nothing shifts on hard braking. Option 2: run L-track along the floor and use Manta Mount cleats to lock the stack down — nearly as solid, fully reconfigurable without touching a drill. The choice comes down to one question: is this van dedicated to your tools, or does it haul people, furniture, or gear on weekends? Dedicated van: bolt through. Multi-use van: run L-track. That's the whole decision. Here's how to execute both.

Before You Start — Know Your Van Floor

Steel Floor vs. Wood Floor vs. Aluminum-Floored Vans

The three most common cargo vans behave differently under a drill:

A custom-floored Sprinter with aftermarket ply installed behaves more like the ProMaster. Know what you have before you order hardware.

Where the Floor Ribs Are and Why They Matter

Every cargo van has structural floor ribs running across the floor. Between those ribs is sheet metal — not rated to hold cargo loads. Every anchor bolt, whether for L-track or a bolt-through plate, must land on or adjacent to a rib. Use a rubber mallet: ribs ring differently than the unsupported skin between them. Mark them with tape before you touch a drill.

One more thing up front: ratchet straps are not a mounting solution. They stretch under repeated load cycles, loosen over time, and fail on hard braking with a loaded stack. What we're building here is positive mechanical engagement — steel to steel, with verified anchor points.

What Tools You Need Regardless of Which Approach You Choose

• Drill with cobalt or titanium bits (rated for steel)
• Tape measure and center punch
• Ratchet, sockets, and torque wrench
• Deburring tool or file
• Safety glasses

Option 1 — Bolt-Through Floor Plate (Permanent, Best for Dedicated Work Vans)

What the PACKOUT Mounting Plate Attaches To and How the Interface Works

The Packout Front & Side Mounting Plate is an anodized aluminum plate that provides the lock points PACKOUT boxes and accessories snap into. You bolt the plate to the floor; the PACKOUT rail system engages the plate's cleats from above. The connection is the same mechanism used throughout the PACKOUT system — no play, no rattle, no improvisation.

Step-by-Step: Bolt-Through Floor Plate Installation

1. Position the plate. Set the base PACKOUT unit where you want it, slide the mounting plate underneath, and find your bolt locations. Each anchor point needs to land on or straddle a floor rib — not open sheet metal. 2. Mark and punch. Remove the PACKOUT unit. Center-punch each hole location. This keeps your drill bit from walking on a steel floor. 3. Drill through the floor. Use cutting oil on steel — it extends bit life and controls heat. Drill slowly and let the bit do the work. 4. Deburr every hole. File down raw metal edges before installing anything. Skip this and you'll corrode from the cut edge outward inside of two winters. 5. Install the backing plate. From underneath the van, slide a steel backing plate over the bolts before you thread on the nuts — size it generously so it distributes load well beyond the bolt hole. This backing plate is what spreads the load across the floor structure. A bolt pulling through a hole in sheet metal with nothing behind it is just a matter of time. Don't skip this step. 6. Torque down with nyloc nuts or thread-locking compound. A loaded PACKOUT stack can hit 150–200 lbs combined. Hardware that works loose will. 7. Engage the PACKOUT. Lower the base unit onto the plate, engage the lock points, and confirm no movement in any direction.

What You Lose — and Why That's Fine for a Dedicated Van

Flexibility. That plate location is committed. Reconfiguring means new holes. For a van that carries nothing except tools, that's irrelevant — pick the right spot, do it once, done.

Option 2 — L-Track + PACKOUT Cleats (Semi-Removable, Best for Multi-Use Vans)

How L-Track Works and Standard Bolt-Pattern Spacing

L-track (also called airline track or logistic track) is an aluminum extrusion with a slotted channel that accepts fittings — cargo rings, fork mounts, and in our case, Manta Mount cleats. It bolts to the floor through its web, distributing load along the track's length rather than concentrating it at single points. Standard L-track bolt-hole spacing varies by manufacturer, so check your specific track's spec sheet before planning your anchor layout. Most van builders run two parallel tracks across the cargo floor width, spaced to match the PACKOUT footprint.

The rule that matters: L-track anchor bolts must hit floor ribs or load-rated anchor points — not the sheet metal skin between ribs. Track bolted to unsupported skin will pull up under a hard stop with a loaded stack.

How Manta Mount Cleats Interface With the PACKOUT System

The Manta Mount cleats are designed by Packible specifically for the PACKOUT rail. Each cleat locks onto the PACKOUT rail at any point along the box — you don't need a full mounting plate, and you're not drilling into the boxes themselves. The cleat engages the same locking slots used by Milwaukee's own accessories. Each cleat is rated at 50 lbs, and a box locked to track releases without tools in about 10 seconds.

Not sure whether to run cleats or a full mounting plate? Our cleats vs. mounting plate guide covers exactly that trade-off.

Step-by-Step: L-Track + Manta Mount Cleat Installation

1. Determine track placement. Measure your PACKOUT base unit footprint — the large toolbox (48-22-8420) measures 19" L × 24" W. Run two tracks at that width plus 1–2" for cleat engagement on both sides. 2. Mark rib locations. Mallet method. Tape every rib within your track run. Every anchor bolt must hit a rib. 3. Cut track to length if needed. Hacksaw or angle grinder with a cutting disc. Deburr the cut end. 4. Position and mark bolt holes. Hold the track in place, mark through the pre-drilled web holes. Only mark locations that fall on ribs. 5. Drill and bolt. Flat washers and nyloc nuts on the underside. Torque to hardware spec. 6. Set the cleats in the track. Spacing should match the PACKOUT rail slots on your base unit. The 6-pack gives you enough for a full base unit with redundancy. 7. Engage and load-test. Put weight in the stack and pull hard in every direction. Zero movement means the install is right. Any flex: check that cleats are fully locked and that the track isn't moving at its anchor points.

Why This Holds — and the One Mistake That Makes It Fail

A properly installed L-track + cleat setup handles practical road loads as well as a bolt-through. The failure mode is always the same: the track got anchored to unsupported sheet metal between ribs because it was easier to drill there. Find the ribs, bolt to them, and this system works.

Mounting PACKOUT on Van Walls or a Shelf System

When Does Wall Mounting Make Sense?

Narrow vans with tight floor plans — short-wheelbase Transit, ProMaster City — benefit from going vertical. Wall-mounted shelf rails free the center floor for larger cargo while PACKOUT boxes occupy wall space.

Using the PACKOUT Front & Side Mounting Plate on a Wall-Mounted Shelf Rail

The Packout Front & Side Mounting Plate works on walls just as well as floors — it provides PACKOUT lock points wherever you bolt it. Pair it with the Packout Tool Rail Side Mount (reversible anodized 6061 aluminum) to configure vertical or horizontal box access in tighter spaces.

Weight Limits: What to Stack High vs. Keep Low

Keep heavy boxes low. A loaded PACKOUT on a wall mount above the wheel wells shifts the van's center of gravity in a way a floor-mounted stack doesn't. Standard PACKOUT boxes are rated for 75–100 lbs each, with rolling units rated to 250 lbs — that's the starting number, but the shelf structure and wall anchor load rating determine the actual limit. When uncertain, consult the van racking manufacturer's spec for your model.

Stack clearance check before you commit: Measure your interior height. A standard-roof Transit has less headroom than it looks. The rolling PACKOUT toolbox is taller than it looks; stacked with a second large box, the combined height adds up fast in a low-roof van. Measure first, configure second.

What NOT to Permanently Mount (and Why)

Here's the insight most YouTube van builds miss entirely: you don't bolt everything down.

The base unit — the one that never leaves the van — gets anchored. The boxes on top that go to the job site, get carried into the house, or load onto a cart? Leave them on the cleat system. They're portable because that's the design intent. PACKOUT is modular: permanently mount the foundation, cleat the top boxes in for transit, and pop them free when you need them at the site. That's the actual workflow.

Permanently bolting your daily-carry boxes means wrestling them off the floor every time you need them. Don't do it.

FAQ

Can you bolt PACKOUT directly to a van floor? Yes. Use the PACKOUT front & side mounting plate as the interface, drill through the floor into the rib structure, and back it with a steel plate underneath to spread the load. The plate provides the lock points the PACKOUT rail system snaps into.

Do I need to drill holes in my van to mount PACKOUT? Not if you run L-track and use Manta Mount cleats. The PACKOUT locks onto the track via cleats without any holes in the boxes themselves. The L-track does bolt to the floor — but that's through purpose-built anchor points, not through the boxes.

Will PACKOUT slide around in a van without mounting? Yes. Even on rubber mat flooring, a fully loaded stack shifts on hard braking or cornering. This is physics, not a "be careful" suggestion. Cleats or bolts are not optional for road use.

What is the PACKOUT mounting plate used for? It's the adapter between the PACKOUT rail system and an external surface — floor, wall, or shelf. It provides the lock points PACKOUT boxes and accessories engage. Without it (or a cleat equivalent), there's no positive mechanical connection between the box and the surface.

Can Manta Mount cleats be used in a van? Yes — it's one of their primary use cases. They mount any single PACKOUT box to any surface with L-track or a compatible rail, without a full mounting plate, which makes them ideal for van floor track systems where you want reconfigurable positioning.

Does Milwaukee make a van-specific PACKOUT mount? No Milwaukee-branded van mount exists at this writing. The PACKOUT ecosystem's answer is the mounting plate and rail system used with aftermarket L-track. The Manta Mount cleat system fills the cleat-to-track interface.

How much does a loaded PACKOUT stack weigh? More than most people plan for. A large toolbox with a moderate tool load is heavy on its own; stack two with hand tools and power tools and you're past 150 lbs without breaking a sweat. Size your anchor hardware for 200+ lbs minimum — including track bolts and backing hardware.

Can a PACKOUT stack fit inside a Sprinter without hitting the roof? High-roof Sprinter: almost certainly yes. Standard-roof vans are tighter. Measure your interior clearance before you configure anything — the rolling toolbox alone stands taller than most people expect, and any boxes stacked on top add up fast. Do this before you buy hardware, not after you've drilled the floor.

Setting up the L-track route? The piece most van builds skip is the cleats. Builders buy the track, bolt it down, and then improvise with cargo straps — which stretch, loosen, and fail. The Manta Mount cleats are the purpose-built lock between your PACKOUT and the track, and they're what makes the system actually reconfigurable when you need it. Pick up the 6-pack when you order the track.
