Estoy muy satisfecho con los productos obtenidos en Vevor por la calidad de sus productos a un precio accesible.

They are working great will buy more when needed. Telling everyone about them. purchased some high dollar ones before and yours are of equal quality. Thanks

nicely made, smooth operation, but no bolts to attach your item to the slide. and they are metric. so its off to the hardware store to get what should have been enclosed. i kind of expected this , but come on already.

this is a really hefty rail to the extreme. extremely rigid and well made.

Exactly what I Ordered, Reasonably Priced and good Quality... Used it and a Router I purchase from VEVOR to construct my own Router Sled. Thank You, Kevin

In combination with a solid carrier rail, this provides the best low profile and strength for a leveling router sled.

Awesome product at a fantastic price. These would have cost ten times as much from Misumi. The quality is rock solid.

The product is very nice but shipping was very slow.

Great product, works well. They should really have the thread size listed either on the product page, or at least with an insert that comes with the product. The thread size on the blocks are M6-1.0, and the mounting holes on the ends are also drilled for M6. Yes, I docked a star for the trouble of having to figure out the thread size via trial and error, as well as thread depth. Which, with internal threads (especially in aluminum) can easily strip/damage the thread start. Also, the threading is about 1/2\" deep on the blocks. 25mm length M6-1.0 cap screws were about 3/16\" too long when mounting a 1/4\" plate. So, 20mm thread length on cap screws.

These rails came in today and are absolutely perfect. The quality exceeded my expectations!
