Appears to be a well bult box. Bought it as a Christmas present for a family member. Nice box for the cost

Great for heavy handtools
The double drawer is fantastic as the slides can hold the weight of heavy fittings and hand tools. It also allows you to stack this box below lid access only boxes.

Klein's three drawer toolbox
This is a great drawer box with just the right depth for me. The long dividers run fromt he front to the back. I like them so much, I have two.

Buy one get one
This was listed as buy one, get one. I put it in my cart, and instead of a second, a combo box was in my basket. I was told that get one is get something. Then it Lowes canceled for reasons unknown to me. Now I know that I will stay clear of Lowes as much as possible

Good quality, sturdy.
Perfect size, drawer depth good for hand tools, very flexible organizer dividers.

The locking bar is genius and looks to be immune from the fatigue issues that plague PACKOUT. I hope Klein comes out with a four drawer box, then they'd have a complete line to battle Milwaukee. I love the three drawer but it would be nice...

Great
This is a great MODBox toolbox. The height of the drawers are perfect for the drill and impact, that my company provided, to fit. I'm expecting to get more tools that will need the added height. I REALLY can't wait for the new Klein MODBox dolly coming out! I will get the 54821MB with it as well.

Misleading Drawer Dimensions
I really wanted to like this. The build quality is VERY solid but, just like the 3-drawer Toughbuilt Stacktech box I purchased and tried before this, the drawer dimensions stated on the website do not match the actual/usable dimensions. I have a full set of Tekton sockets. The deep sockets are all 3" tall and the organizers they're in are 1/2" tall for a total height of 3.5" tall. The ModBox specs state the drawers are 3.5" tall so I thought "cool, my sockets will fit." Wrong! Because of the pa...
