4pcs T Type 2020 European Standard Anodized Aluminum Profile Extrusion Linear Rail for 3D Printer Parts and CNC DIY Laser Engraving Machine 200mm(7.874inch)

I bought 6 sets of these in different lengths and am highly impressed. Sturdy, precisely formed, cleanly cut, individually wrapped in protective plastic, then boxed. They all arrived in excellent condition, no dings, dents or bends. There were a few minor burrs on the ends from the cutoff saw, but they were so minor 1 or 2 strokes of a fine file removed them. Honestly, if I didn't have a file I could have left them as is--VERY nice!

Très bien usinés et à bon prix. Installé pour réaliser une pergola en extérieur.

These aluminum extrusions are accurate to the stated dimensions, and well machined. I used them to add linear rails to a 3D printer, and found them to be straight and free of any warping or manufacturing issues.

Cut to size and all same length, quality built, clean of scraps and easy to thread.

Worked fine for what I needed it for. A bit pricey though.
