This 4040 V-slot aluminum extrusion is a sturdy, anodized black profile with two T-slots on each side.

It's 40mm x 40mm, available in lengths from 100mm to 1000mm.

The V-slot design works with wheels for smooth linear motion, and the T-slots let you bolt on panels, brackets, or other components.

Great for DIY makers, workshops, or prototyping.

The surface is smooth, corrosion-resistant, and looks professional.

Easy to cut and assemble with compatible connectors.
