Hart Stack System is Awesome.

Hart Stack System is awesome. I have not overloaded it either. I have made a Soldering/Desoldering Field/Lab Kit. Now I am making another kit for my 1/2" CR-MO Impact Sockets/Wenches, Work Light Kit, %26 20v Batteries/Charger Kit.

I purchased this add on stack box, because I use it for storage of essential items for our vehicle (Emergency kit, jumper cables, windshield fluid etc.). These are very sturdy. The construction is excellent.
