Features
- Aluminum Diamond Tread Plate: ATB builds the A-MC crossover box from aluminum diamond tread plate, made to handle road vibration and weather extremes.
- Medium or Heavy Duty: Choose the A-MC3 for medium duty or the A-MC4 for heavy duty, as ATB rates them.
- Low-Medium Profile: The low-medium profile and slanted sides and lid sit lower across the bed, and ATB includes the mounting hardware.
- Push-Button Locks: Push-in tamper-resistant locks give the break-in protection ATB designs into its crossover boxes.
- Gas Spring Lid: The single top-open lid lifts on self-powered gas springs, and an extra deep opening makes cargo easier to remove.
- Pro-Sliding Tray: A sliding handy tray keeps small tools on top and within reach.

The mounting hardware is included.

Frequently Asked Questions
Will it fit my full-size pickup?
ATB says its full-size crossover boxes fit full-size trucks. Measure rail to rail and compare with the width in the table.
How do I measure for a crossover box?
Measure your bed rail to rail (outside edge to outside edge) to choose the width, then check the depth against the bed space you want to keep and the height against your rear window and any rack.
What is the difference between the A-MC3 and A-MC4?
ATB rates the A-MC3 as medium duty and the A-MC4 as heavy duty. Both have the same tread plate build, push-button locks, gas spring lid and sliding tray.
Does it come with mounting hardware?
Yes. ATB includes the mounting kit.
What is the difference between -TT and -TTBX?
-TT is bright aluminum diamond tread plate; -TTBX is the same box powder coated textured black.
Can I see into the box from both sides?
No. The A-MC has a single top-open lid; for access from both sides of the truck, ATB offers gull wing crossover boxes.
