ToughBuilt 4-Wheel Cart, Tool Box Dolly for StackTech Toolboxes and Organizers - Heavy-Duty Rolling Base with Locking Casters, Tie-Down Points and Automatic Lock System

This is well made. The casters are heavy duty, roll well, and are large enough in diameter to handle most surfaces. I have them in my garage so I can't speak to how well they deal with gravel but they do fine on smooth and rough concrete and other surfaces. Full sized Stacktech boxes lock in easily when placed on this car. Overall this is a great cart. I'm writing this review because I found no other reviews that mentioned if the rolling toolbox bases can sit on top of this cart. I ended up getting a bundle with a rolling toolbox base, a drawer box, and an organizer. I was hoping that the rolling toolbox would sit level on this cart, but it does not. The wheels get in the way and won't let it settle into the cart. The rolling toolbox bases don't have the same locking mechanism but I was hopeful that it was still designed to be used with this cart. Looking at the tailgate transport hitch you can see that there are cutouts to accommodate the wheels so I guess it makes sense. Overall, I'm still very impressed with the whole Stacktech ecosystem but it would've been nice if the rolling toolbox base could sit level on these rolling carts. I am a home user but I can imagine trades folks wanting the rolling toolbox to transport and then putting it all on this rolling cart once they're on the job site.

These things make moving all of my toolbox stacks around much easier than the bottom, wheeled toolbox.

Works well. Only two wheels lock, but that’s no biggie for me. YMMV. Very sturdy, and now two Stacktech crates and one toolbox are easy to move about in my garage. Yay, Stacktech!

Nothing "Stacks up" to ToughBuilt!!! LOVE this ToughBuilt StackTech series. I have purchased almost all of the different box units and accessories. Looks and it super rugged. Get compliments on it all the time, looks super tactical and turns heads. They click and lock togeter so nicely and seamlessly. I was the entire collection!!! I purchased and love them all: Rolling swivel base - great for rollign your stack around the warehouse or your shop Extendable handle wheeled cart - great for taking stacks on the go Locking boxes of different sizes - lots of options for different stacks setups. Boxes with sliding drawers - lots of options for different stack setups. Cup Holder with Toughbuilt tumbler - take your drink with you! Wood worktop top piece - place my laptop on this while rolling around the shop. You can still open the lid of the b8x you mount this on, so you done have to take it off each time. Love this accessory , allows you to put the different ToughBuilt trays on it. They lock securely in place and are super easy to remove and place on another part of your box stack. JUST GET THESE! I looked at all different brands and nothing quite "stacks" up to these!

Very happy, but I’m not using it for a cart. I didn’t attach the wheels and secured it to the floor of my van. It works fantastic. Very happy with all of my Stack tech purchase. Hoping more Stack tech items are released. Unfortunately the company is not doing very well and I’m not sure if Stack tech will be available much longer.

I finally got this after waiting over a year for this to come out and found it here at Amazon! This thing is perfect to have at home in my garage with my 3 drawer and 2 single drawers and crate on it, Easy to move around in the garage for working on my truck or around the house.

I’m a handyman, and ToughBuilt has really become one of my go-to brands. This cart has been a game-changer for me — sturdy, practical, and makes my work so much more efficient.

I don't know if it was mishap or it was intended but I got 2 of them when I only needed 1 it works as intended for my needs probably going to add some more stack tech.
