1. Better Built Top Mount Tool Box - Overall Best Top Mount Tool Box

As you can tell from the name, this product wants to sell itself on quality. Even though it weighs only 55 pounds, it’s durable enough to hold your tools and protect them from weather damage.

This Better Built truck tool box is 60 inches long and 12 inches high. That’s enough space to store most tools, from power tools to smaller ones like wrench and screwdriver sets.

The truck tool box is made of 14-gauge steel with a diamond-tread aluminum-plated black finish. This plating is designed to be rust resistant. We also love the tool box’s compact size. It is sleek enough to sit on your truck without obstructing your view or keeping you from loading the truck bed properly.

If you think about it, you only need your truck tool boxes to fill a few needs—protecting and organizing your tools while not negatively impacting the overall look of your vehicle. The Better Built top mount tool box hits all these targets.

  • Long 60-inch length for extra space
  • The product package includes T-cup latches
  • Some varieties come with two doors
  • Provides great weather resistance for your tools
  • Some customers complain that it’s dented on arrival due to shipping
  • You need an extra pair of hands to install it properly

The Better Built Top Mount Tool Box is an excellent choice. It has a large interior, 14-gauge steel walls, and a rust-resistant coat. This is the kind of tool box you can mount and use for years.

2. Lund 8272 72-Inch Aluminum Professional Top Rail Mount Box - Best for Aesthetics

The Lund 72-inch top rail mount box has a diamond-shaped aluminum plating with a rust-proof electrostatic finish and silver color. So, what makes this product so great?

For one thing, this aluminum tool box has a limited lifetime warranty that protects it, and thereby your wallet, against defects. Its design is also deceptively simple. The plated finish is also a beauty to look at. It complements nearly any truck quite well.

Now, let’s talk about the interior. The Lund top rail mount box is 72 inches long, 12 inches wide, and 22.5 inches tall, making it incredibly spacious. And because it’s sturdy and made of 0.06-inch aluminum, it will protect your tools just fine.

We also love how the aluminum tool box has two separate doors that open in opposite directions. When they are shut, they close up securely, protecting the content, regardless of how bumpy the ride is.

  • Has a lot of room for your power tools
  • The doors open in both directions
  • Sleek design that looks good on most trucks
  • Diamond-shaped aluminum plating that only weighs 44 pounds
  • It is an aluminum tool box, which isn’t quite as tough as steel
  • Doesn’t come with mounting hardware

If you need a tool box that’s both aesthetically pleasing and spacious, you can’t go wrong with the Lund Aluminum Professional Top Rail Mount Box. It also has a tough, lightweight construction that is easily accessible.

3. Better Built 64210149 Top Mount Tool Box - Best for Portability

You may be disappointed that this Better Built truck tool box is only 48 inches long, but that’s actually the beauty of it.

The tool box storage will sit neatly on the edge of your truck bed, leaving plenty of room for anything else you need. Its portable size isn’t the most alluring thing about this toolbox; instead, you’re more likely to enjoy its durable and sturdy build.

For a tool box with such a small size, it’s one of the sturdiest we found during our research. It’s made of 14-gauge steel and weighs 69 pounds unloaded.

But there are some other great things about this product, like T-cup latches for easy access and the full aluminum hinges. It also comes in white or black.

  • It could be larger
  • The product only has one door

If you have a small pickup or just prefer to save space in your truck bed, consider getting a portable top mount tool box like the Better Built. It also has a strong frame and accessories that make its use convenient.

Things to Know Before You Buy

If you’re getting a heavy duty tool box for your pickup, the best options are either aluminum or steel. Truck tool boxes made of these materials have a reputation for being sturdy, durable, and excellent at protecting your tools.

Plastic tool boxes are becoming more popular because of their lightweight and low cost. However, they tend to perform poorly on pickups because they’ll go through a lot of exposure and everyday wear and tear. Just think about all your metal tools clanking around in there. You’ll have more longevity with a higher-quality design.


There are two Better Built tool boxes on this list, but our number one recommendation is the Better Built Top Mount Tool Box. It has a simple design, 14-gauge steel construction, and a decent amount of interior space. On the other hand, you could also buy the Lund 8272 72-Inch Aluminum Professional Top Rail Mount Box if you’re looking for something a bit more aesthetically-pleasing.
