Description: These aluminum beams are great for making unique links and connections in your Actobotics project thanks to 9 thru-holes running its length and are sold in packs of two. Each beam has a length of 3.08", a width of 0.375", a thickness of 0.25", and utilize the 0.77" hub pattern.

Actobotics is a robotics building system based around extruded aluminum channels, gears, precision shafts, and ball bearings. Thanks to the two standardized hole patterns, nearly all Actobotics components can be intuitively connected together. The wide range of components makes building complex electromechanical prototypes or finished projects a reality.

Note: The length of these beams is calculated from the center of each thru-hole at opposite ends, the over-all length is 3.455".
