This hard to find adapter helps create a free standing sign neatly and completely. The adapter inserts into our heavy duty cast iron base (part number IS-GP5-BASE), and locks into place with the Lock Bolt provided on the base. A 3" diameter post can then be inserted into the adapter for a very sturdy application. There are 3 set screws around the perimeter of the adapter to tighten the post into place. The amount of free-standing signs you can create now are limitless!
