Simple metal tool holder. Attaches to studs in the wall or drywall with the included drywall anchors. I've tested different sizes of power tools and most fit perfectly, but some larger bits have to be inserted backwards if the chuck is too big. They can also be hung on the battery. Haven't found a double that doesn't fit yet, almost any battery powered L-shaped tool will work. I was even able to fit a large 1/2" torque wrench and this mount handles the weight with ease. The holder can also be mounted on a perforated panel and you can either screw it down or attach it with a nut and bolt. I use perforated metal plates so they can easily support the weight. I have a little problem with the edges of the slots. They aren't sharp, but they do have an edge that can scratch more delicate surfaces like hard plastic, mostly if you hang the instrument upside down. Not a huge issue, but something to watch out for if your tools need to be in pristine condition for whatever reason. All of my tools are worn out from use, so it's not a big deal to me. pretty basic apart from the "Ztorq" branding cut out of the metal at the top of the bracket. You can put a sticker on it if you don't want to see this branding, it's really not that noticeable when you mount the holder up with the tools in it. All in all a pretty decent mount. My tools took up valuable closet space and the fact that they are hanging and easily accessible was an improvement for me. I only keep the 4 most used tools in a holder and the rest in my pantry.
