4pcs 200mm T Slot 2020 Aluminum Extrusion European Standard Anodized Linear Rail for 3D Printer Parts and CNC DIY Black(7.874inch)

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.

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

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

I bought these to make a top-hat for my Voron Trident. There's nothing wrong with the extrusions. Be careful though: The outer dimensions are the same as what you would see from an LDO kit, but the center hole cannot be tapped for M5. You'll have to tap the center for M6. Make sure you have the hardware on hand. Also, these are anodized aluminum with a perfectly reasonable finish, but if you compare it to the finish of your LDO kit you will be disappointed.

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.

using this for a small fixture. each wrapped in clear tape on 2 sides, then wrapped in light foam. No damage whatsoever.

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.

Fits well
