For use with our Liberty and Commodore Stands, these spare inserts taper down the bore hole to accomodate poles smaller than 1 1/4" in diameter.  Sold as a set each one shrinks the diameter by 1/8".  Use one for poles 1 1/8" in diameter and use both for poles 1" in diameter.  3.5" in total length and made from a sturdy black plastic.
