These did what they claim they do. No issues with these so far, at all. So I ordered more as I have many uses for them.

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.

Good quality, great buy

Saved myself thousands using these rails to build a router sled. Great ball bearing action, heavy stainless rails, solid. Great choice for any heavy-duty slide applications.
