Using this Avenger A2014 C - Stand Column is easy. First, make sure your base has a 28mm receiver. Then, attach the bottom of the column to the base using the 28mm female bottom receiver. The top attachment with 16mm can be used to connect other equipment. To adjust the height, simply extend or retract the three sections until you reach the desired height between 60cm and 139cm. When it comes to maintenance, keep the column clean by wiping it with a soft, dry cloth regularly. Avoid using harsh chemicals that might damage the chrome - steel finish. Also, store it in a dry place to prevent rusting. And always check the connections before use to ensure safety.
