Using this Actobotics Channel Mount for your Arduino is super easy. First, take the pair of mounts and snap them onto an aluminum channel. Then, simply press - fit your Arduino Uno or Mega on top of the mounts. When arranging the mounts on the channel, you have many options, so you can choose the setup that best suits your project. As for maintenance, keep the mounts clean and dry. Avoid using them in very wet or dirty environments as this could affect their performance. If the mounts get dirty, you can gently wipe them with a dry cloth. And remember, since they're made of Delrin, they're lightweight but still quite sturdy, so handle them with normal care.
