Video Transcript for RC Manufacturing Z-Series Truck or Trailer Underbody Tool Box Review
Speaker 1: Today we're taking a look at the Underbody Truck or Trailer Toolbox. Now, this toolbox is designed to mount under your truck or trailer to provide some extra safe space for your gear. It's made from a steel construction, so it's very strong and durable. It does have a powder coated finish on it, which keeps it safe from rust and corrosion. And one of my favorite features is that it has a really nice textured finish on it, which gives it a really nice rugged look.The t-handle right here is made from a stainless steel construction that allows for very easy operation. Also, with that handle you don't have to worry about rust or corrosion buildup.
To open the box, you lift up on that t-handle and you simply just rotate it and that allows the unit to open. You'll notice that it has two chains, one on each side, that way you don't have to manually hold the door open as you load your gear or as you remove your gear from the box.Also, around the perimeter, it does have a built-in seal. This keeps water and dirt out of the box and it keeps your gear protected. Plenty of space on the inside. Located right here is the lock and it comes with two keys, so the box is lockable to keep your items safe from theft.
Again, keys are included. Down here at the bottom of the door, it does feature a really nice heavy duty hinge for years of use.Really nice construction all the way around the box. Really nice welds on the unit. And when it comes to the dimensions, the overall length from edge to edge, that measures 30" long. The overall height from bottom to top, 18".
And then the overall depth, that's from front to back, that also measures 18". Now, when it comes to mounting, you'd want to use two RC001 mounting brackets. Mounting brackets and mounting hardware are sold separately, but it does come with detailed installation instructions to help walk you through that process step by step. That's going to do it for today's look at the Underbody Truck or Trailer Toolbox.

Great box. Very heavy duty. 4 stars because of the price. You could buy a gun safe for the price. However with a better lock this could be used as a safe. Very well built heavy steel box.

It was damaged during shipping. I guess the delivery person drug it in the garage scraping the paint off the sides.
Other than that the tool box looks good. Just hate spending so much money to have it damaged during shipping.

Name tag in picture is off, it's an RC Box. Great boxes, this was a replacement box due to the last one getting destroyed when the truck got t-boned by a honda civic. The box and honda were totaled, the truck was unscathed. Great box, would definitely recommend.
