Heavy duty, well made, simple design and install.Pro/ConPro- heavy duty- well made, easy installation- hold my Makita power tools in a far easier to grab configuration than my old shelf- solid mounting hardware included - I only used the screws- versatile if you have some DIY skillsI have 2 work areas - garage and basement along with 2 work benches, winter/summer.In my garage, I mounted 1 power tool holder and 2 shelves. I ripped a 2x4 and cut it to 51 inches long. I screwed the 2x4 to the wall framing every 16 inches. I then screwed the 3 shelves to the face of the 2x4 - very solid.In the basement shop, I have yellow metal pegboard backed up by wooden framing behind. I simply screwed the power tool rack through the metal per board into the wooden frame - once again, very solid.Some folks complained about not having the ability to attach these units to pegboard. You can attach them if you install a wooden backer behind the peg board. There’s always a way to solve a problem.If you lack DIY skills, you might have issues with installation.For me, this was a solid acquisition. Hope that helps!
