80/20 15 Series Aluminum Extrusion - 3x0.75 Inch T-Slotted Rail For DIY Projects (24 Inch Length)

For makers, builders, and DIY enthusiasts, this 80/20 aluminum extrusion is basically adult LEGO for building pretty much anything you can imagine.

This particular profile is the 3034-Lite model - a 3 inch by 0.75 inch rectangular T-slot with two open T-slots on the 3-inch face.

The 15 series designation means it's compatible with all the 15 series brackets, fasteners, and accessories you can find online.

It's made from 6063-T6 aluminum with a clear anodized finish that both looks good and provides corrosion resistance.

The 24-inch length gives you plenty to work with for various projects, and the quality is what you'd expect from 80/20 - clean cuts, deburred ends, and tight tolerances.

The align-a-grooves along the sides are super handy for keeping everything straight when you're connecting multiple pieces.

People use this stuff for everything from building 3D printer frames, workbenches, and laser cutters to automation equipment, machinery guards, and even furniture.

The open T-slots mean you can slide nuts in from any direction, which makes assembly and adjustments much easier than with closed slots.

Whether you're prototyping a new invention, organizing your workshop, or building custom fixtures, this extrusion system gives you incredible flexibility without needing welding or complex metalworking skills.

It's seriously strong yet relatively lightweight, and you can reconfigure things as your needs change.

Once you start building with T-slot aluminum, you'll find uses for it everywhere in your shop or workspace.
