Using this Actobotics crossover plate is quite simple. First, find other Actobotics products you want to attach it to. Then, connect the plate to them according to the design. When attaching 1' tubing, align it with the inner 1.5' hub pattern. You can use the outer flanges to connect tube clamps or other mounts. For mounting 1' tubes perpendicularly, make sure to position them correctly. As for maintenance, keep the plate clean and dry. Avoid using it in harsh environments that may cause corrosion. If there are any parts that seem loose, check and tighten them regularly. When storing the plate, keep it in a safe place where it won't get damaged.
