2020 T-Slot Aluminum Extrusion, 10 Pack 1200mm Black

2020 aluminum extrusion T-slot profiles give your builds a straight, rigid frame for smoother motion and accurate alignment in 3D printers, CNC machines, laser engravers, and DIY automation. This 10-piece set uses European-standard 20×20 mm anodized 6063-T5 aluminum for corrosion resistance and consistent fit with common T-slot hardware. Precision-cut, burr-free surfaces help reduce friction and wear, keeping assemblies running cleaner with less rework.

• Delivers a rigid 20×20 mm frame base to improve stability for printers, CNC, workbenches, and enclosures.


• Includes 10 rails plus fasteners and corner connectors for quicker builds and cleaner, repeatable assembly.


• Fits M4, M5, and M6 T-slot nuts for broad compatibility with modular extrusion systems.


• Reduces friction with precision-cut, smooth surfaces designed to minimize burrs, wear, and maintenance.


• Resists corrosion with an anodized finish suited to humid shops, garages, and long-term installations.

Build faster without welding or custom machining—these modular T-slot rails let you prototype, expand, and reconfigure frames as your project evolves. Use them for linear rail supports, machine guards, router tables, custom furniture, or automation stands where alignment and repeatability matter. With included connectors and M5 hardware, you can start assembling right away and fine-tune later with standard T-slot accessories. Grab yours today and lock in a dependable foundation for your next build.
