The rails were sturdy and well-made, providing a smooth and precise operation. I was so impressed that I decided to buy an additional 2-piece rail set, and I couldn’t be happier with my decision.The delivery was incredibly fast—my order arrived a full five days ahead of schedule, just one day after placing it! The packaging was also excellent, ensuring the rails arrived without any damage. The seller clearly understands the importance of careful packing and timely shipping, which added to my positive experience.Overall, I am thoroughly satisfied with this purchase. Whether you're a hobbyist or a professional woodworker, these rails are a fantastic investment. I would definitely recommend this product to others!

As expected at a great value

I have been searching everywhere, and there is no mention of the hardware size that will fit the rails. I have a 2040 v slot and still have no clue what hardware I need to attach the rail to the 2040.

These work really well just as descrived

top quality

Everything is good except the ball bearings are low quality. When sliding the moving piece snags on the rod and grinds.

Just what I needed to make my router flattening jig
