2040 T-Slot Aluminum Extrusion, 4 Pack, 1000mm Black

2040 aluminum extrusion profile rails deliver a rigid, modular frame system for smoother motion and more accurate builds in 3D printers, CNC machines, and DIY automation. This 4-piece set uses European-standard T-slot design and an anodized 6063-T5 aluminum alloy body for corrosion resistance and clean sliding surfaces. Precision-cut edges help reduce friction, simplify alignment, and keep assemblies serviceable as your project scales.

• Delivers stable, square framing for linear rails, printer gantries, CNC frames, benches, and enclosures


• Reduces friction with smooth, burr-free surfaces for cleaner travel and less binding during motion


• Fits common T-slot hardware with side-groove channels compatible with M4, M5, and M6 T-slot nuts


• Supports fast customization with modular profiles—build, extend, or reconfigure without welding


• Resists corrosion with anodized finish suited to humid shops, garages, and maker spaces

Upgrade or start your next build with consistent, repeatable components that make alignment easier and changes faster. These 2040 T-slot aluminum extrusion rails are lightweight for handling yet strong enough for rigid structures, helping your motion system stay true over time. Use them for 3D printer frames, laser engraver setups, automation equipment, or furniture-style builds where clean lines matter. Hardware such as nuts and bolts is not included—grab yours today and spec your fasteners to match your design.
