4PCS T Slot 4040 Aluminum Extrusion Profile 39.4'',European Standard Anodized Linear Rail for 3D Printer Parts and CNC DIY 1000mm Black(39.4inch)

I’m just starting to learn how to use extruded aluminum but I really like the material and fitting options. Easy to cut with a table saw and a Metal cutting blade.

I used two of these to create supports on my Trak Racer monitor stand to mount a shelf for my PC, and they worked perfectly. The quality is right on par with the pieces from Trak Racer, and the finish is essentially identical, so it blends in perfectly. The T-slot channels are a little bit deeper than the Trak Racer pieces, so the T-nuts don't hold quite as securely in them, but that wasn't an issue for my use.

cost effective alternative for wood. No power machines required, cuts neatly cuts easily etc. Framing for use as table or cabinets, adjustable shelving certain to outlast everyday family activities.

Good product

Good stuff!

I bought these to attach Ford Focus ST seats to my Simlab P1-X Pro racing rig. I wanted a real car seat with adjustability, but how to mount them? These worked perfect; used angle brackets and hardware I also got on Amazon and it worked perfectly. If you use a different car seat make sure the mount points are all on the same level and angle.

Good extrusion that seems accurate dimensionally. One star off because there are some slight rough cuts on the edges, but overall very worth the price. Packaged well, too. Would purchase again.

These ones have a slight different slot fitment than the standard 80/20 bars. So hardware might be a bit floppy at first. Once tightened though they works exactly as expected. Great lower cost and readily available solution.
