Frequently Asked Questions

Q: What lengths are available for the V-Slot 2040 aluminum extrusion profile?

A: This V-Slot 2040 black anodized aluminum profile is available in lengths ranging from 100mm to 800mm, including 100mm, 200mm, 300mm, 400mm, 500mm, 600mm, 700mm, and 800mm. Simply select the length that fits your CNC, 3D printer, or woodworking project build.

Q: Is this aluminum extrusion compatible with standard V-slot components and hardware?

A: Yes. This profile follows the EU standard 2040 V-slot specification and is fully compatible with standard T-nuts, angle brackets, V-slot wheels, gantry plates, and other common linear motion hardware — making it easy to integrate into existing builds or start a new project from scratch.

Q: What is the benefit of the black anodized finish on this aluminum profile?

A: The black anodized coating provides a hard, protective layer over the aluminum surface, improving resistance to corrosion, scratching, and everyday wear. It also gives the profile a clean, professional aesthetic that suits both functional machines and display-worthy custom builds.

Q: Can this profile be used for both CNC machines and 3D printers?

A: Absolutely. The 2040 EU standard V-slot profile is one of the most widely used structural extrusions in both CNC router and 3D printer builds. Its dual-rail 40mm width offers excellent rigidity for gantry systems, frame construction, and linear guide setups in both applications.
