    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

    Good quality, decent price, and accurate length. Also, all 6 side are anodized. I would (will?) buy them again.

    I’ve bought a lot of silver anodized 20 x X (40, 60 and C type) and never encountered quality like this before! Exactly (ok I do not have a vernier or micrometer this large but…) the same length, I bought two 500mm pieces and stood them side by side on my surface plate. With 10x magnification I could not discern any difference in length, nor could I see any machining marks where they had been cut! There were between 2 and 4 tiny burrs evident within the profile on one end of each piece, and they were insignificant and did not extend beyond any contact areas that would negatively impact any build or joint. On both pieces the ENDS were also anodized, I have only ever seen raw aluminum on end faces in the past, and I have bought quite a few lengths from other vendors! T nuts, both drop in and sliding, fitted perfectly and were standard 5mm size, plus the pilot holes in the ends were 4.2mm and perfect for 5mm x 0.8mm tapping. Great quality and added to my favorites for minimal cut builds for CNC and 3D printer projects I have in mind.

    Great pacakaging. Nice and clean. No metal shavings.

    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.

    The pieces came in with sharp edges and all 4 are exactly the same length. These pieces are excellent versatile with the V slotted profile. Highly recommend these.

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

    This is very standard 2020 V-Slot rail, but it appears to be of good quality, with a good surface finish with no scratches. All 4 pieces were perfectly straight and had no apparent leftover metal shavings anywhere that I could see. Additionally, it even had a nice black finish on both ends, which is often not the case. When measured, it was also dimensionally accurate to within a hundredth of a millimeter -- which is VERY good. I would expect this to work great in either a 3D printer or CNC machine. The only reason I am not giving this 5 stars is because it is a bit pricey for what it is, but the quality is excellent and may be worth it if you are looking for something with a really nice, smooth finish.

    The ends are anodized, seems to be good quality and a good value.

    The width lets me add stability to my vertical test bed, for motherboards.
