90 Degree Positioning Squares Aluminium Alloy 4.7" x 4.7"(12x12cm) Right Angle Clamps Woodworking Carpenter Tool Corner Clamping Square for Picture Frame Box Cabinets Drawers

Ordered these after looking at the Woodpecker version. I thought I would take a chance on them for the price. I will say that I am pleasantly surprised. The measurement markings on the side are about 1/32 of an inch off as compared to my DelVe. They are all square also. They will work with the fence clamps I got from MilesCraft. Though the clamps will not go all the way through holes on the square. The clamp can be use where the hole is larger on the other side of square, just realize it does not go all the way through the hole. The slotted area does allow the clamp to go all the way through. I did find that every square had areas where the coating got removed and showed bare aluminum. This was found only in the holes of the square. See pictures for more clarification. Overall, they will work for me and the most important part is that they are square. Yes the rulers on the side are nice, however I would not use them if you are doing fine precision work on a piece. Most woodworkers will find the squares accurate enough.

I didn't think through how this clamp works. Of course the pressure is on the edge of the clamped material. This causes the tab on the outside to rock up towards the edge, not sitting flush, which then doesn't grab firmly unless you tighten so much you cause indents into the wood. I use small bar clamps with the corner bracket.

Super high quality - better than expected. Buy with confidence !

Gotta say, nice simple packaging that really shows off these Anodized Aluminum Positioning Squares. And they are damn pretty! These can be used for many different applications. They are very at home with T- Trak Systems and Clamps. They seem kinda pricey, but a bit under the other comparable offerings on Amazon. There are plastic versions that are less and would let you have more Squares for similar money, but I don't know how they would hold up. And these are Very Nice! The lettering is great, they are on Prime and came on time. Cool.

I have several rafter squares that I usually use when putting projects together for square, but also some combination squares when needed. I ordered these, mostly because I like red, but also because these looked like they were going to work well when I needed to clamp things together, more so that rafter squares. I like them and they are very sturdy. These do seem they aren't totally accurately square, but pretty close. Though it could be a problem of my other squares. These work fine for putting cabinets together though.

Nice tolerances at a fantastic price. I was surprised by the quality of the squares at this price.

I like the aluminum construction. I also like the measure markings on the side. While these were expensive for what they are, they were much less expensive than comparable products offered on Amazon. I am satisfied with them.

I am so glad I picked up a set of these! Already used them on 4 projects. I am considering picking up another set as well!!

Nice quality and really useful to have imperial and metric measurements, they also look nice in the workshop 😊 if you’re for ever glueing or joining right angle Thea are a must

Millimetre scale is 3mm out on both.

Really good and worth the money

These are ideal for holding small work pieces @ 90 degrees prior to fixing.
