These aluminum box extrusions are robust and lightweight solutions for custom robot frames, superstructures and mechanism construction. Made to all of your favorite English sizes, the classic 2x1 thin wall tubing is now joined by its thicker-walled counterpart. We have also introduced two thicknesses of 1x1 sizes that teams know and love to build their medium-sized mechanisms.
For smaller mechanisms, we recommend using our 5/8 square box tube that is also compatible with our S3 line of brackets and gussets.
Available Sizes:
Be sure to all check out our Gussets as they work wonderfully with all of these wonderful extrusions.

This aluminum clamp-on shaft collar has a 0.5 in. hex bore. A 8-32 x 0.5 in. socket head cap screw allows for adjustment.
This simple bracket handles so many of your mounting needs! Mount motors or gearboxes anywhere and make axle supports with bearings - it's a do-it-all, put-it-anywhere bearing and motor mount bracket.
Any motor or gearbox with a 2-inch diameter bolt circle can be mounted in this bracket. The center hole is sized to hold a standard 1.125 inch outside diameter bearing.

Each hub now has a "flower" pattern that fits and keys into our 42T 5 mm HTD Pulley, which means you are no longer constrained to our legacy 500EX Hex Hub for compatibility with this pulley. Every hub still maintains a closed-profile hole for maximum strength. Every shaft hub has been designed with bearing bosses on both sides that have been sized appropriately for the mating bearings that would pair with the bore through the hub, which means you can run each hub right against a bearing with no need for extra spacers. All of these hubs are also made from 7075-T6 aluminum, which is much stronger than the previously used 6061-T6, 6005, and 6105 alloys from our older designs. Where possible, the shoulder on shaft hubs was reduced to 7/8" in diameter for an easier fit with our molded plastic wheels, while still maintaining a precise 1.125" diameter boss for locating in wheels, sprockets, gears, and more.
The holes are evenly spaced on a 1.875 in. circle and 0.201 inches in diameter. That's a perfect size for #10 bolts!
