This is Integral's trades bundle for 2019+ Chevrolet Silverado / GMC Sierra 1500 and 2020+ Silverado / Sierra HD: an Integral Bulkhead Rail across the front of the bed plus a two pack of Stack Locks, the latch that holds Milwaukee Packout organizer stacks. Put the toolboxes in when you need them on the job and pull them out in seconds when you need the bed for something else. Your tools ride in the bed instead of the back seat, and you don't give up the bed for good to get there.
How the Stack Lock works
Each Stack Lock is a spring-loaded latch built to grab the aluminum side rails on full-size Milwaukee Packout organizers. Clip a stack on, clip it off. The Slide-N-Latch mount lets each Stack Lock slide along the rail and latch wherever you want it, and stacks can face forward, backward or sideways, so you can lay out the front of the bed around how you actually work.
Fitment
Fits all bed lengths on 2019+ Chevrolet Silverado 1500 and GMC Sierra 1500, and 2020+ Silverado HD and Sierra HD (2500/3500). Not compatible with Carbon Pro beds. The rail bolts to factory mounting points; no drilling or permanent modification. It works with any full-size Packout organizer that has side rails — not compact organizers or rolling chests without them.
What's in the box
One Integral Bulkhead Rail with one tie-down cleat, and two Stack Locks with the hardware to mount them. Packout organizers and the other accessories in the photos are not included. The bundle is priced below buying the rail and two Stack Locks separately.
Questions before you order?
Fitment questions are easier to settle before the box ships. Call or text Carl & Anton at (920) 249-7744 or use the chat — real humans in Sheboygan, Wisconsin, not a call center.

Stack Lock Toolbox System FAQs
Do I need to buy Milwaukee Packout boxes separately?
Yes. The bundle includes the rail and two Stack Locks. Stack Locks accept any full-size Milwaukee Packout organizer with aluminum side rails.
Can I take the toolboxes out quickly?
Yes. The Stack Lock is a spring-loaded latch, so a Packout stack clips on or comes off in seconds and the rail stays in the truck.
Does installation require drilling?
No. The bulkhead rail bolts to factory mounting points in the bed and the Stack Locks mount to the rail.
Can the stacks face different directions?
Yes. Each Stack Lock slides and latches anywhere along the rail, and stacks can be mounted facing forward, backward or sideways.
