2020 T-Slot Aluminum Extrusion, 4 Pack 1200mm Black

2020 aluminum extrusion profile rails deliver a straight, rigid frame base for CNC builds, 3D printer upgrades, and laser engraving jigs. This 4-pack of 1200 mm European-standard T-slot linear rail features anodized 6063-T5 aluminum for corrosion resistance and consistent alignment. Precision-cut, burr-free edges help reduce friction and wear, while the slot design supports fast, reconfigurable assembly without welding.

• Includes 4 × 1200 mm 2020 T-slot rails, 9 pairs of M5 nuts/bolts, and 4 cast aluminum connectors for quick builds


• Delivers stable, square framing for automation equipment, workbenches, enclosures, fixtures, and DIY machinery


• Supports M4, M5, and M6 T-slot nuts to simplify modular add-ons, brackets, and repositioning


• Resists corrosion with an anodized finish suited for humid shops, garages, and long-term setups


• Reduces snagging with smooth, burr-free surfaces for cleaner motion paths and lower maintenance

Build cleaner, straighter assemblies with a modular T-slot system that’s easy to cut, join, and expand as your project evolves. The 20 × 20 mm profile balances strength and weight for frames, rails, and structural bracing—ideal when you want adjustability without welding. Use the included connectors and hardware to start assembling right away, then scale your machine, workstation, or enclosure with compatible fasteners and accessories. Grab yours today and move your build from planning to assembly.
