Review: Exceptional Linear Rail Kit, smooth and precise. - Exceptional Linear Rail Kit, smooth and precise. I used this with a SpecTool Router Sled Kit. These rails precisely fit together with this sled and perform excellently. I'm very impressed with the rollability of these rails. They are smooth and durable. Overall construction is superior and resulted in a very professional router sled for my use. I am more than pleased. I did contact the seller with a couple of questions, and they quickly and accurately responded. It was a very nice experience. Highly recommended!

### ⭐⭐⭐⭐ Great rails but with just a little bit of flex
*by L***X on July 28, 2022*

Great rails but with just a little bit of flex. I used these for a router sled. There were two drawbacks. The first was hunting for the correct screw size of the holes on the mounting blocks. (Metric6 by the way) The second if a little bit of flex in the rails. For a full size router I may have to go back and add some steel underneath the rails so they don't sag.
