Features
- Aluminum Plate Build: ATB builds the A-TM41 from .090 smooth and .100 diamond tread plate aluminum, fully seam welded on all seams and corners.
- Gas Spring Lids: Channel braced, reinforced lids open with the help of gas springs on a full-length stainless steel continuous hinge, with a deep opening for getting tools out.
- Stainless Lift Handle Latch: A lockable stainless steel lift handle latch secures each lid; ATB calls the lock tamper resistant.
- Adjustable Galvanized Dividers: Galvanized 18 gauge hemmed dividers adjust to your tools and parts, over a rubber mat on the floor.
- Adjustable Lock Striker Seal: An adjustable lock striker pulls the lid down onto an automotive-type weather seal for a positive seal.
- M3200D Mounting Kit Included: The box comes with ATB's M3200D mounting kit and mounts on a flatbed, a flat surface or a service body rail.
Description & Fitment
The ATB A-TM41 is a low-profile aluminum top mount compartment box, 6" tall and 14" deep, for flatbeds, flat surfaces and service body rails. It has a smooth aluminum body with diamond tread plate lids that open on gas springs and lock with a stainless steel lift handle latch. Inside are adjustable galvanized dividers over a rubber floor mat. ATB includes the M3200D mounting kit, and the box is made in the USA.
Fitment & Compatibility
How to choose: measure the flat surface or rail where the box will sit (the length available and the 14" depth front to back) and allow room above for the lids to open, then pick a width from 48" to 96".
Widths of 48", 60" and 72" have a single lid; 82", 84", 90" and 96" have double lids. The version table lists lid opening and weight for each part number.
Fits: Flatbeds, flat decks and service body rails; top mount (check the width chart)

Frequently Asked Questions
Will it fit my truck?
The A-TM41 mounts on a flatbed, a flat surface or a service body rail. Compare the box width and 14" depth with your mounting area; contact us if you want a second check.
How do I measure for a top mount box?
Measure the flat surface or rail where the box will sit: the length you can give it and the 14" depth it needs front to back, plus room above for the lid to open. Then pick the width.
Does it come with a mounting kit?
Yes. ATB includes its M3200D mounting kit with the A-TM41.
What is the difference between single and double lids?
The 48", 60" and 72" boxes have one lid; the 82", 84", 90" and 96" boxes have two lids. The version table shows the lid opening for each size.
Can I use it with my underbody boxes?
ATB says its TM Series boxes can be mounted on a flatbed, a flat surface or a service body rail and used together with its SG and SR Series boxes.
Will it keep water out?
An adjustable lock striker pulls the lid down onto an automotive-type weather seal for a positive seal against rain and road spray.
