To use this 90-degree hub mount, simply attach it to the Actobotics channels in your desired position. Then, insert your 0.5' diameter shafts or tubes into the two 0.5' bores. Make sure to align the mount with the 0.77' hub pattern for a proper fit. When handling the mount, be careful not to drop it as it could get damaged. For maintenance, keep it clean and dry. If it gets dirty, you can use a soft cloth to wipe it. Store it in a cool, dry place when not in use to prevent rust or other damage.
