Professional Tool Reviews for Pros
What’s your favorite tool storage system? Packout? TStak? Something else? After looking at what the Flex Stack Pack has to offer, you might just change your mind.
The classic stackable tool box system has been around for a long time. Take various box depths with the same length and width, and give them a way to connect the bases and tops. At first glance, that’s what the Flex Stack Pack storage system does. Even at the foundational level, there are worthwhile talking points.
It starts with the boxes themselves. They use a durable tool plastic, similar to other premium stackable systems. The lids feature a gasket to keep water and debris out.
Organizer boxes with interior buckets nest into the lid to prevent items from wandering around. The latches hold securely and recess on the back side so they’re not snapping down on your fingers when you close them.
While there are other options to get those premium features, now we start to dive into where the Flex Stack Pack begins to set itself apart.
The stacking locks are the easiest we’ve used. To lock one box on top of another, simply set it on the lid and press down once you have them lined up. It’s that easy.
To release a box, push out on the locks until you hear them click. They hold themselves open so you can adjust your grip or grab the handle and carry it away. When you take the top box off, the locks spring back into place, ready to accept its return.
In case you’re wondering, Flex’s design does include half-box interlocking. Conveniently enough, the hybrid jobsite fan just so happens to fit that half-box size perfectly. Coincidence? I think not.
Looking at the three Flex Stack Pack tool boxes that come as a set, it has a higher weight capacity than others. Combined, it can hold 500 pounds. Milwaukee’s Packout set is rated for 425 pounds and DeWalt’s TStak set holds 470. Other options from Craftsman and Ridgid are under 150 pounds.
We have to talk more about the lids. The medium box and rolling box have gas strut lids. Yep, no more holding the lid open with one hand while trying to grab a load with the other and wishing you had a third. Whichever member of the design team pushed for this addition, thank you!
As far as Flex is concerned, the outside of your tool box is fair game for storage, too. There are several exterior storage accessories you can add and they are legit.
The cord wrap and, level holder are self-explanatory, but I want to spend a little more time on the attachment racks, mainly because they’re a brilliant idea. Tools with belt hooks and rafter hooks hang on them and we love the security that avoids knocking them off the top and not having to bend down to pick up our tools from the ground.
They’re also compatible with battery holders. In addition to mounting on the outside, they also mount on the insides of the rolling and medium tool boxes. Best of all, they just slide it, so you can store batteries on the mounts inside and then pull the whole mount out and set it on the outside rail while you’re working.
Between holding tools and batteries outside the box, you now have more convenient access to the tools you’re using at a height that beats picking things up from the floor any day of the week.
In addition to the tool boxes, there are also Flex Stack Pack cases that hold accessory sets. Inside the medium and rolling boxes, the lid has connection points to hold Stack Pack cases.
The connections of these cases are more minimal, and it takes a little getting used to. One side is fixed and the other has a spring-loaded button. Set the fixed side into one slot and then snap the spring-loaded side into the other. Despite the minimalist look of the connection, we find that it holds the cases securely.
There are multiple connection points on the underside of those lids, making any size Stack Pack case compatible.
The same connections to the lid also connect the cases to each other. If you need some extra space, you can pop the cases onto the lid and add another layer to them if you like.
At the moment, the only pricing we have is for the 3-in-1 rolling tool box set. Look for it at Lowe’s, Acme Tools, and other Flex retailers for $279.
The deeper we dove into the Flex Stack Pack tool storage system, the more impressed we were. It makes improvements to the basic design of stackable tool boxes, adds premium features you find from other brands, and then takes it to a whole new level with concepts we haven’t seen before. Flex Stack Pack is redefining what you can expect from your toolboxes and everyone else is playing catch up.
