OUYZGIA 2040 Aluminum Extrusion 350mm 14 inch V Slot 2040 Extrusion for Building 3D Printers CNC Machine (V Slot 2040, 14 inch, 350mm, 2pcs)

These are exactly as described and well made. This for me is gonna be part of a cnc routers gantry system.

Ive ordered so many rails and I think these are the best looking ones Ive received. They are just so well made with such an outstanding finish. As I said, just beautiful. Cant find any flaws. Come packed every well also. Fantastic rails, fair price, would gladly recommend.

Its 2020 v-slot aluminum. The nuts I used with it fit fine, I didnt compare pricing with any other sources, but it worked perfectly for my needs.

For those not on the metric system, these are 23.5 inches long. They measure exactly 20mm in height and width. These have a smooth anodized finish over the entire surface, including the ends. They are straighter than I have the ability to measure. Should work for lot of purposes, including the CNC setup

These are perfect! They are just what I expected. They came neatly wrapped and have a very clean finish. Even the ends have a matching finish. There are no shiny cut ends.⭐️⭐️⭐️⭐️⭐️

I have ben getting a lot of these extrusions that come shipped with aluminum bits all over them. These came wrapped well and clean. The finish is excellent and they are straight!

They work great, look great and both ends on each piece were either painted to match or anodized. Both pieces were flawless and I will purchase this brand again.

These aluminum extrusions were what I needed to extend a small laser cutter. Standard tslots fit with them and the black coating has held up well.

I picked these up so I could add some parts to reinforce my 3d printer, and this is exactly what I needed. The sizes are easy to select, and theyre exactly the same type of extrusions (2020 aluminum) that are used to build the frame of my 3d printer. The edges are chamfered and not sharp, and the channels (v-slots) fit the typical extrusion assembly nuts without any issue. These are a good value for the price, definitely recommend if youre looking for 2020 extrusions

These are excellent Aluminum rails. I use them primarily for upgrading my 3D printers and these do the trick. Very accurate, the length and widths are spot on and every thing links together well. The black coating on the outside feels and looks nice too. It’s great there is a good variety of sizes too so you don’t have to worry about cutting to length.
