Multi Angle Degree Corner Clamps, Adjustable 30-90 Degrees Sawing Mitre Right Angles Measuring Cutting Tool for Woodworking Photo Frame (red)

This "clamp" did not work for me. It is made of plastic and does not hold the pieces of wood (1x2 pine) securely in place in order to screw together or to glue. My one project called for a triangle shape and this "clamp" did not work. My other project called for a rectangle and this "clamp" would not even work for 90 degree angle.

This is interesting, I really like the variable angle design.It is simple yet clever.Easy to use, and clamp your workpieces in.The main concern I have here is the materials it is made from.I have other wood working plastic clamp tools that are fine, and made from a more dense higher quality plastic, this is not quite up to that same standard.The plastic you can tell is a little cheaper.It is overall decent, but I do have some quality questions.For instance, it clamps tightly and accurately, however I am concerned with how much clamping force you're putting on the mechanism, that it may not last super long.When I first got this and was articulating the sliding angle adjustment on it, a screw just fell out of the bottom. It had red plastic on the threads, and looks like it was over tightened and stripped out some of the plastic in the hole.This seems to do the job fine, especially for smaller and more light weight projects. If this breaks within a few projects, I'll probably come back and lower the star rating. For now, it is merely a suspicion that it may have some problems after repeated use - but so far it is a hunch and unfounded.This same tool in aluminum or a higher grade plastic would be great, as it is, still recommended because it seems to work well, even if I am mostly going to be using the 90 degree angle, it is nice to have options.

I have a metal corner clamp, but it was pretty pricey. This is a nice alternative to the expense versions. It's a thinish plastic, but once it's clamped in place, it holds well. If you wanted to glue picture frames, this is an affordable way to buy 4 and get the whole thing set in a day

This tool is not really a clamp. It’s more of a third hand. I say it’s not a clamp because it does not exert any direct pressure against the two faces being joined. What it does is just hold them in place next to each other. It could still be handy to hold two pieces in place while you fix them together in some other way, for example, by screwing them together with pocket screws, but it would not be useful for gluing without screwing because no direct force is being applied against the two adjoining faces. They are just being held in place next to each other.The tool is made from lightweight plastic, so it does not feel sturdy. The largest size piece of wood it can accommodate is a 2x4 (maximum 3 ½ inch width). I suppose you could put a 4x4 in it, but the clamping part would only be putting force on the bottom 1 ½ inches of wood, so it would not be very secure. I don’t think there is any minimum size as the clamping parts will slide up and down anywhere between 3 ½ inches and 0 inches. The two sides work independently, so you could clamp different size pieces of wood together, though I am not sure why you might need to do that! Inches are marked along one side and centimeters along the other, so I suppose you could use those edges as a 6-inch ruler if you wanted to. The combined angle of the two pieces you are joining is shown along the sliding semicircular part, which is useful. It could be a double check that the angle you cut is what it is supposed to be (just in case you have trouble adding two angles together when you’re cutting them on your miter saw!).The insides of the clamp seem to be the same hard plastic as the rest of the clamp. (I couldn’t find the rubber part mentioned on the website. The inside parts are ridged to grip securely. If you were working with a very soft wood like cedar, the ridged parts could mar the wood, so you might need to put something between the wood and the clamp to protect the wood.My biggest concern is the light weight of the plastic combined with the amount of force required to lock the sliding clamps in place. You really have to put a lot of force on those thin plastic handles to pull them up and lock the clamps down. When I was doing that, I expected the tool to break at any moment, but it didn’t. Maybe the plastic is stronger than it seems. One other concern I had was that the wood will be held in place along two edges of the clamp, but there is nothing to support the underside of the two corners that are being joined together. I think I would want to cut a piece the height of the tool and put it under the corner I’m joining to provide some additional support there. I would also screw the clamp to the workbench. Fortunately, there are some holes in the tool so that you can do that. Overall, it’s a lightweight tool that might be useful as a third hand, but if you want something that actually exerts some direct force to push together the two pieces you are joining, this is not the tool for that.

I've been trying to get these to work for me but honestly, just not that great. Cheap plastic and not truly accurate. It's good enough for getting corners to hold together while tapping in a couple of brad nails for shop furniture or things like bird houses but nothing too thick or too heavy. Make sure you have your corners dead accurate because the jig just isn't,

These are okay as a lightweight positioning aid for small material. The material clamps don't really "clamp" they just keep the pieces pointed the direction you want. They lock in place but don't apply any significant pressure. The locking cam is all plastic and requires enough force to lock that there is a fear of breaking the locking tab off. Having said that, I've locked and unlocked them several times and they seem to be able to stand the force. The angle measurement seems spot on. I checked it with a good protractor. The locking pins, angle set screw, and the main pivot are all metal and are well made. The material clamps can take up to 3.5 inch width. If you need to handle larger stock or if you need significant clamping pressure, this is probably not the corner clamp you need. If you primarily use smaller stock and just want a jig to hold things in the right orientation long enough to do what you need to do, this may work for you.

The media could not be loaded. This seems to be a pretty cheap plastic. I can't get lock tabs to lock the slides into place. It does expand by releasing the knob.i guess it's OK for some small home projects but not for big projects that need good tools
