Why Overlanders and Trades Pros Appreciate This Lock

Overlanding and Adventure Use

• Locks your Packout stacks in place during camp stops, overnight parking, or trail side breakouts—so recovery gear, cooking supplies, or spare parts won’t walk off.
• Prevents accidental Packout stack removal or shifting during rough terrain, trail driving, or over-landing travel, keeping gear securely where it belongs.
• Ideal for integrated truck bed rail systems—mount the lock to Integral or Unistrut rails, then stack and secure Packout organizers for modular, customizable gear storage. Overlanders can trust that their mounted gear stays locked when camp is set.

Trades, Contractors & Tool Truck Applications

• Create a theft-resistant Packout storage zone in your truck bed or trailer—tools, fasteners, and jobsite gear stay locked in place during transit or when parked on-site.
• Perfect for carpenters, electricians, and contractors who want to leave frequently used Packout tool boxes mounted behind the cab or in a trailer while minimizing theft risk or unauthorized access.
• Quick, tool-free lock/unlock design means you can mount your Packout stack for work and lock it down for travel without needing to remove or reconfigure your setup each time.
• Helps reduce tool theft or loss when trucks are parked overnight or left unattended on remote jobsites, delivery stops, or camping zones.

Installation & Use Tips

1. Choose your mounting surface (Integral Rail, Unistrut, truck bed wall, trailer, or van panel).
2. Bolt or mount the Ultimate Packout Lock to the rail or flat mounting surface using the supplied hardware—or your preferred mounting hardware if using a custom setup.
3. Stack your Milwaukee Packout organizers onto the locking plate or mounting rail. Once stacked, engage the locking pin.
4. When locked, Packout boxes cannot slide off or be removed without unlocking the mechanism. Unlock when ready to access your tools or gear.
5. When not in use, keep the lock covered or sealed to protect the locking cylinder from mud, grit, or moisture.
6. Periodically check and clean the lock mechanism, especially after exposure to dusty, muddy, or wet environments, to maintain smooth operation and prevent corrosion.
