10pcs T Type 2020 Aluminum Extrusion 39.4'',European Standard Anodized Linear Rail for 3D Printer Parts and CNC DIY 1000mm Silver(39.4inch)

Used these to frame up solar panel mounts for my sailboat. They are great, and survived over 40 knot storms on the ocean and haven't rusted or anything.

Great for Lego style building. Wish it was cheaper.

This extrusion is clean and well made and a great price. That said it has an issue if you plan on using hardware on the ends of it. Most 2020 aluminum extrusion hardware is designed to use 5mm M5 screws in the bore that you tap to put a M5 machine screw. This one has a 6mm bore which can only accommodate a M6 screw, which most likely has too large of a screw head to fit in the hardware, unless you get special M6 screws or alter them yourself. I am not really dissatisfied as the slightly larger 6mm bore allowed me to run a 18/3 solid wire cable through it, but it was an issue that is worth mentioning to others.

These are good extrusions, but don't trust the "1m" length is accurate. Mine had a noticeable length variation, maybe +-2mm, and the ends were not square. Count on cutting them yourself. Apart from that, they're nice.
