4pcs 400mm T Slot 2020 Aluminum Extrusion European Standard Anodized Linear Rail for 3D Printer Parts and CNC DIY Black(15.75inch)

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!

I recently purchased 10pcs 48inch T Slot 2020 Aluminum Extrusion European Standard Anodized Linear Rail, and I was able to get an open box set for a great price. The value for this product is excellent, especially if you are collecting extrusions for a build one day.The aluminum extrusions are well-made and durable, with a smooth and consistent anodized finish. They are also very versatile, as they can be used for a variety of projects and applications, from building furniture to creating custom 3D printers.Despite being open box, the extrusions I received were in excellent condition, and they were packaged securely to prevent any damage during shipping.Overall, I would highly recommend 10pcs 48inch T Slot 2020 Aluminum Extrusion European Standard Anodized Linear Rail to anyone looking for a high-quality and versatile building material. The value is excellent, especially if you can find an open box set for a discount.

These were exactly cut for my project and doesn't scratch with durable anodized (not painted, i have gotten some that was painted) My 3d printed T-Bolts worked great also.

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

The price is great, but the anodizing is weak. Look at it wrong, and it scratches. Other than that, it’s a great value for the money.

Perfect for my project.

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.

Wow, I am impressed with the quality, strength and appearance of these extruded aluminum rails! I am already thinking of other projects to build with these. Highly recommend and will be back to purchase more.
