2020 T Linear Rail – European Standard: Our aluminum extrusion rail includes 10 aluminum alloy rails (47.24 in / 1200 mm each), 21 pairs of M5 nuts & bolts, and 10 cast aluminum connectors—everything you need for easy setup! Built to Last: The anodized linear rail is made from durable 6063-T5 aluminum alloy with an anodized finish for excellent corrosion resistance. Whether it's humid or dry, these rails are designed to stand the test of time. Smooth and Precise: Cut with high precision for smooth, burr-free surfaces. This means less friction, smoother operation, and more reliable performance. You’ll notice the difference in both efficiency and lower maintenance costs. Easy to Customize: The side groove design works with M4, M5, M6 T-slot nuts, and more—making assembly a breeze. Ideal for your DIY projects and fast builds. Designed for Structural Applications: This T-slot aluminum profile is ideal for building sturdy frames, workbenches, display stands, and protective enclosures. Note: Due to the non-beveled V-slot edge, this profile is not suitable for roller-based linear motion systems
