4pcs 300mm T Slot 2020 Aluminum Extrusion European Standard Anodized Linear Rail for 3D Printer Parts and CNC DIY Black(11.8inch)

Exactly as described. Packaged great and not a scratch on any of them - most had a protective film on multiple sides and they were all wrapped individually in thin, soft packaging foam. They were able to be cut clean and smooth with my normal medium aluminum miter blade. The silver finish is sharp - unlike the black coated profiles, the scratches from normal cutting and building are practically invisible (they also feel smooth, not like a chalk board like the black coated ones).Probably states this in the description, but will verify in case anyone is curious:- These are T-Slot, not V-Slot- End tap is M6, not M5

I used these and other lengths which I cut to custom lengths (along with other parts), to build an open air enclosure for the battery on my scooter build. It turned out incredibly rigid, and exceeded my expectations. I'll be using more of this product on future projects for sure. Very pleased. Thumbs up!

Packaged really well and easy to work with. We built our entire conversion using these along with M5 and M6 hardware. The extrusions are extremely strong and straight.

These pieces are incredibly substantial and have proven to be greatly versatile. These will be utilized on many future projects

This 48" T Slot 2020 Aluminum Extrusion is great for any DIY project. It's easy to use and cut to size, and the aluminum is strong and durable. I've used it for a variety of projects and it's held up well. The slots make it easy to attach other components and the overall quality is great. Highly recommended for anyone looking for a reliable and affordable aluminum extrusion.

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.

This came neatly packed, no damage or marring, accurately described. Wish the price was a bit better but that's me, my point of reference for costs of any goods is stuck circa 1998-1999. It sucks getting old. Anyway, very pleased and it's working well for a 3D printed telescope project I'm working on.

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.

Fits well
