Solid and Super Handy
This was my first time using a set of setup blocks such as these and I would highly recommend them to anyone putting together a basic set of woodworking tools. The set includes two angled setup blocks along with four sets of bolts/nuts/clamping blocks. All pieces felt solid in construction and held firmly regardless of the workpiece’s thickness. The two angled setup blocks showed dead 90 degrees when measured against my digital angle gauge. All in all an excellent addition to my home woodworking shop.

That's Exactly RIGHT°
If you work with wood assemblies that you make yourself, you can't escape 90-degree corner assemblies. Regardless of whether your join is flat edge or 45° angle cut, you need a way to maintain the corner join while your glue dries or to assemble with screws, staples or brads. If you've been blessed with 4 arms, you're all set, but if not, your extra set of hands can be found with this awesome 90-Degree corner jig from WEN. In addition to being your extra set of hands, this jig holds your corner to precisely 90°. I've discovered this jig is well suited for most sized projects, excluding very small assemblies. It is made of a sturdy metal construction (not hardened plastic) that should last a lifetime. I heavily recommend this WEN corner jig tool.

Get two or use brads. Either way, your work will look professional with these square corners.
These positioning squares are really nice for holding that corner square while you check that everything is right. The squares are sturdy and have plenty of holes to give you options on where to place the bolts. I thought the laser etched numbers were just to make it look nice, but they came in handy a couple of time on my project last weekend. The bolts are also nice and square and extra long so the square doesn't have to be placed flush with the top of the box. I am by no means a professional carpenter. I wanted to build some simple drawers to hold some tools in my garage. I wasn't looking for pretty and I grabbed some cheap plywood that I had on hand (go for the nicer stuff it will make it easer). I used these clamps to hold the corners while the glue dried. My only complaint was that I only had two. Boxes tend to have four corners and it would have been faster if I also had four clamps. That said, these are not "clamps" they are "positioning squares". I believe they are used to hold a corner in place while you put in a few brads or staples. I was concerned those wouldn't hold in cheap plywood, so I waited for the glue to dry. I'm still an armature, but I now I corners are square.

Great clamping squares for smaller jobs
I was able to use these squares and clamps today for help in constructing drawer boxes for a workbench/cabinet and they worked very well for these smaller components. They are constructed extremely square and are very accurate. The clamps hold tight but they are a little fidgety setting up as the hold down blocks want to turn until snugged up. I know they aren’t primarily made for this purpose but I used them to set up my saw today and they were spot on. I also used them just to check square and were at 90 just as they should be. These squares are very robust and should last a very long time.

Extra set of hands
I've been doing woodworking for 40 plus years and have tried different jigs. This 90-Degree Precision Positioning Square was like having an extra set of hands that didn't talk back. I used this yesterday I had to make a drawer frame. On my first miter cut I used two 90 Degree squares to lock in corner. After nailing I had one Positioning Square in each side then continued to nail and repeat to the frontside. This jig was a timesaver. I wish I had this product when I built my last bookcase. I also used this precision 90 Degree square when setting up my jointer. The compact size allowed me to use during setup for my CNC. I find it a very useful multifunction quality built tool for my workshop.
