    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.

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

    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 sturdy extrusions. I have used them in a few projects. they are strong. the black finish is a nice touch. They are also cut to the right size from the start. 5/5

    Its difficult to review these - its exactly what I expected and as advertised. Each piece was individually wrapped, theyre straight and true. No damage or defects. Im using these to extend the Z axis on a 3D printer and theyre just what I needed.

    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.

    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.

    I got these to build a new larger format 3d printer. Ive been using 2020 (vslot) rails for years to build printers. These ones in particular are very good looking because the ends are also anodized, so Im assuming they dont anodize these until after theyre cut, which Ive never seen and appreciate the effort. My only gripe is theres not internal threads in these. Not a big deal for my application, but it may be for somebody else. Otherwise, perfectly straight and nice and sturdy even at 600mm.

    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

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