2040 T-Slot Aluminum Extrusion, 5 Pack 2000mm Black

2040 aluminum extrusion T-slot profiles deliver a rigid, modular frame base for 3D printers, CNC builds, and automation projects. Each rail is precision-cut from 6063-T5 aluminum alloy and anodized for corrosion resistance, helping maintain smooth travel and clean assembly. The European-standard 20x40 mm design supports fast, repeatable builds with common T-slot hardware when you need reliable alignment and scalable structures.

Whether you’re upgrading a 3D printer frame, building a CNC enclosure, or prototyping a linear rail structure, these anodized T-slot extrusions keep your build accurate and easy to modify. The modular design lets you expand or reconfigure without welding, making it ideal for iterative DIY and professional shop projects. Note: T-slot nuts and bolts are not included, so you can choose the exact hardware for your application. Grab yours today and start your next build with a strong, compatible foundation.
