Description
High-Precision & Robust Construction: Made from 6063-T5 aluminum alloy, these profiles offer an excellent strength-to-weight ratio. Precision extruded and anodized for a smooth, wear-resistant finish that resists corrosion and oxidation.
Versatile V-Slot Design: Features European-standard 2040 V-slots with smooth, deburred edges for safe handling. Enables effortless and flexible positioning of components using standard M3, M4, or M5 T-nuts along all four sides.
Superior Rigidity & Stability: Provides a straight and rigid linear rail foundation critical for accurate motion in 3D printers and CNC routers, minimizing deflection and ensuring consistent performance.
Extensive Compatibility: Fully compatible with all 20-series aluminum profile accessories (connectors, brackets, hinges). Serves as the ideal skeleton for a vast range of structural and motion applications.
Wide-Ranging Applications: Perfect for building or upgrading 3D printer frames, CNC routers, CNC gantries, laser engravers, robotic arms, and automated systems. Also ideal for industrial workbenches, lab equipment, exhibition displays, ergonomic furniture, and advanced DIY tech projects.
Precision extrusion
Extruded aluminum extrusion have the advantages of low cost, light weight, high strength and durability.
High cutting accuracy
Professional cutting, high cutting accuracy, good flatness and high quality.
2040 Extruded aluminum extrusion has a very tight tolerance range, ensuring that the DIY process will not be bothered by dimensional issues.
The tolerance range of the automatic cutting machine is small, only ±0.5 mm.
Anodizing
Anodizing process can significantly improve the corrosion resistance of aluminum alloys, increase the surface hardness and wear resistance of aluminum alloys, and have good decorative properties.
High strength aluminum extrusion
Made of 6063-T5 material, the v-slot has smooth edges.2040 V Type aluminum extrusion profile also fits T nuts.
Main alloying elements of 6063 are magnesium and silicon in addition to aluminum, with excellent processing performance.
Good extrudability and corrosion resistance and excellent anodizing effect.
Widely used in construction profiles, pedestals, furniture, machinery, etc.
Ideal for 3D printer and CNC build
Aluminum profile extrusion products are a good linear motion material with high strength and adjustable.
Applications: automation equipment, professional 3D printers, workbenches, lasers, stands, furniture, etc. machinery, fitness equipment, precision printers, automatic cutting machines, etc.

Common questions about buying open-box and refurbished.
Why buy refurbished or open-box?
Refurbished and open-box products offer the same performance as new at a fraction of the price. You're already saving $3 on this listing. They've been inspected, tested, and are ready to use — the only difference is the price tag. Buying refurbished also reduces electronic waste, extending product life cycles and keeping functional devices out of landfills.
What's the difference between open-box and refurbished?
Open-box products are customer returns that have been inspected and confirmed functional. They may show little to no use — often the item was returned simply because the buyer changed their mind. Refurbished products have been professionally repaired or restored by technicians, tested to meet or exceed manufacturer specifications, and sometimes come with a warranty. Both are a smart alternative to buying new.
Why use OpenBoxFox?
Finding refurbished deals is time-consuming — you'd have to check Amazon Warehouse, Reebelo, Dyson Outlet, and others separately for CtopoGo products. OpenBoxFox aggregates these listings in one place, so you can compare and find the best deal without the legwork. We update pricing daily so you always see current availability and real savings.
Is it safe to buy refurbished?
Yes. Products listed on OpenBoxFox come from established retailers like Amazon, Reebelo, and Dyson — not unknown third-party sellers. Each retailer has buyer protection policies, return windows, and in some cases warranties. You get the price advantage of used goods with the purchase security of a known retailer.
