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!

Kudos for shipping them with full individual plastic wrap and cushioned tube packaging. Great product, impeccable finish.

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.

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

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.

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.

Perfect. Used for custom camper cabinetry, a kids light table, straight edge for cutting. Versatile and high quality.

Excellent material to work with. It’s great for structural support projects!
