I needed some rails for a project I am building and decided to try these. The quality was great, I found them to be of very nice quality, smooth operation and built well. The Stainless rails were very, very hard and should resist wear well. I am very pleased and would purchase these again, and will should the need arise.

When I received these rails, I was very impressed with the quality material used for these pieces! These are perfectly machined and not made with flimsy, substandard materials. You just don't see this type of quality much anymore. They easily handled the load that I used them for (but rated much higher) - with very smooth gliding action. I can't say enough about the quality of these pieces - and at an affordable price! Would highly recommend these rails for most any application where quality is critical.

Very little backlash or movement. Not sure it is use it for machinist precision, but excellent for wood working level precision.

I bought these and some other rails to flatten some slabs from a tree I cut up. No complaints here. I bought a Bora Centipede table and screwed them down to 1/2" plywood. Unfortunately, the plywood bowed. I recently purchased the Bora t-track tabletop mdf panel and I am currently trying to figure out a way to install this in the t-track. I want to mount the rails in such a manner that I don't have to screw into the wood and I can add spacers underneath to elevate the rail.
