2040 T-Slot Aluminum Extrusion, 1000mm, 5-Pack

2040 aluminum extrusion T-slot profiles create a rigid, modular frame for 3D printers, CNC builds, and automation without welding. This 5-piece set includes black anodized 6063-T5 aluminum rails cut for smooth, burr-free motion, helping reduce friction and keep assemblies aligned over time. European-standard 20x40 mm geometry supports widely used T-slot hardware for fast, repeatable DIY builds and upgrades.

• Delivers rigid 20x40 mm structure to improve stability for frames, linear rail mounts, and machine enclosures


• Includes 5 extruded rails, each 1000 mm long, for consistent builds and multi-axis projects


• Supports M4/M5/M6 T-slot nuts for quick assembly, adjustments, and add-ons (fasteners not included)


• Reduces drag with precision-cut, burr-free surfaces for smoother travel and easier maintenance


• Resists corrosion with a black anodized finish suited for humid shops, garages, and workspaces

Build cleaner, straighter assemblies with a 2040 T-slot aluminum profile set designed for repeatable results. The side-groove design makes it easy to mount brackets, panels, jigs, or accessories and reconfigure later as your project evolves. Use it for a 3D printer frame, laser engraving rig, CNC machine base, workbench upgrades, or custom furniture where strength-to-weight matters. Check your required nut size and cut plan before ordering, then grab yours today and start your next build with a solid foundation.
