The 32mm Pulley Plate is one of two pulley plates available in the S3 Ecosystem. Two of these plates in conjunction with standoffs, screws, and a nub create an effective and robust winch, am-3729 (coming soon). It has a central bolt pattern for an AndyMark XL Nub (am-3441a) or the 0.770 in. bolt circle used with the Actobotics building system. The outside diameter of this plate matches the root diameter of a 24 Tooth Ninja Star Sprocket (am-3283). This allows it to be used as an idler chain guide. Specifications:
