Upgraded 340mm Track Saw Square Right Angle Circular Saw Guide Rail Angle Stop Accessories Compatible with Festool and Makita Guide Rail (Red)

I didn't expect much for the price, but figured for the price if it would allow me to quickly do rough parking lot breakdowns of materials they won't cut at the big box (MDF/Melamine, etc.) it'd be worth it. First, it does indeed work with my M18 track (see pictures) and locks in very securely, though I wish the clamping pressure were adjustable as it feels very tight almost like something will bend. Second, I did a quick check with my Veritas square (accurate to 0.001 per inch) and it was surprisingly square (see pictures). I'll update the review after making cuts if something unexpected happens, but overall this is a decent product.

Works great with my Milwaukee track saw and track. Square and stays square. Seems well made for the price, and is adequately sized even for my longer track. It actually made me realize that two of my shop squares were not perfectly square. Over an 8-ft distance it looked like it wasn't lining up properly to my marks when in actuality the squares that I used to make those marks were not square. Two of my higher quality squares match this perfectly

I got this for my Wen track saw, and sadly it is not good. It fits the track fine, but it is not square! And there is no adjustment to fix it to square! I attached it to my track, and using a framing square, it was out by 1/16th at 14" from the guide. In case this was error in the square, I got another one it was the same. Finally, I made a test cut on 4ft plywood and the cut was off my nearly a 1/4 of an inch!! I checked the square for any way to adjust it, and there is no way. I tried some painters tape on the show that goes into the track, so it would be held askew, but that was not sufficient to correct it. I am refunding mine and now I have to wait for a better one to be delivered. Project delayed!!

I took a chance to see if it would fit my Grizzly track but it won't. But I'm a handy person so I'll see if i can machine it to fit. It is very well made and a bargain price. If your brand is listed I would recommend it.

This was square from the package and works well with the Festool track. For a discount imported product the fit and finish is pretty good and it’s been a useful tool at a good price.

It works, and is decent quality. However the clasps are really cheap. Unlike the more expensive products like this, it does not have any plastic coating on the clasps so I am always afraid they are going to damage my expensive track saw rail. It does have a long rail to go in the underside of the rail - but this is both good and bad - more stable but also it jams up with the under rail clamps that share that rail. Its a good price though, so I keep it around to use once in a while.

If youre looking for a good one of these to buy then buy this one. I had one before this with tightening screws and it was short and it sucked. This one works perfectly

At first I thought it was not square BUT I was using a carpenters 24” square to check it. Turns out that too, built to build walls, was not square. Shame on me for thinking contractor tools are meant for maximum accuracy. They are made for building walls, not cabinets. Lesson learned. This device was dead on 90 degrees. A bargain.
