About these item Durable Aluminum Alloy: Made from 6063-T5 aluminum alloy, these T-slot aluminum extrusion rails feature an anodized surface that helps resist corrosion, oxidation and scratches. The sturdy construction supports reliable use in indoor and outdoor environments. Available in 2020, 3030, 4040 and 4080 profiles, these extruded aluminum rails provide versatile framing solutions for equipment assembly, furniture, workbenches and DIY projects. Precision-Cut T-Slot Rails: Each aluminum extrusion profile features precisely cut slots with smooth edges for convenient assembly. Factory-tested straightness helps maintain alignment when constructing 3D printer frames, CNC machine structures and other equipment supports. The T-slot design accommodates compatible sliding nuts and brackets, allowing components to be positioned and secured along the rails. Multiple Profile Options: Choose from seven configurations with 2, 4, 6 or 10 rails per set. The 2020 profiles support M5 T-slot nuts, the 3030 profile supports M6 nuts, and the 4040 and 4080 profiles support M8 nuts. Center hole diameters are 5 mm for 2020 rails and 6.8 mm for larger profiles. These options help match different frame dimensions, fastening requirements and assembly needs. Convenient Frame Assembly: The T-slot structure allows rails to connect using compatible nuts, screws and brackets without welding. Each set includes an accessory kit and user manual for straightforward installation. The modular design makes it easier to assemble, adjust or expand frames for changing project requirements. Self-tapping screws for the center holes are not included, so select suitable fasteners when needed. Versatile DIY Applications: These anodized aluminum extrusion rails are suitable for 3D printer frames, CNC machine structures, workbenches, furniture, display racks and custom equipment supports. Smaller 2020 profiles suit compact assemblies, while 3030, 4040 and 4080 profiles offer larger cross sections for different structural designs. Ideal for makers, workshops and custom fabrication projects requiring flexible modular framing.
