excellent manufacturing, mounting blocks glide effortlessly.

These are smooth operating and seam to be of good quality.

I used this product for a slab flattening jig with my router. Even with a very dusty environment, the bearing slides easily, maybe even too easily as I went off the end of the rails once, but that is really my bad. I wish that there were female threads at the end of the rails inline with the rail axis to facilitate adding a stop to prevent going off the end. When it went off the end, a single ball bearing did dislodged and was lost, but that still didn't prevent it from moving smoothly on the rails even after that.

I am very pleased with these rails. I am building a Sliding Table Saw attachment to use these on.Great price and service.

Smooth sliders, using for router sled

I bought what should have been two pairs of compatible rails from the same supplier but the hole locations for the blocks do not align with the mounting holes for the rails. Which then requires brackets to be made to mount one pair of rails on to the other pair of rails. Poor design!

they were nice i am building a router sled and i needed all parts the same dia

Great product, just as expected.
