This is for the pole only - no mounting bolt on bottom so if you have a  1/2" quick release, this should fit right in. If you don't have a quick release already, look for my listings that include the quick release to save you on shipping, or look for the listing that includes a mounting bolt on the bottom instead.
These poles are perfect for the larger 2'x3' and 3'x5' safety flags used on most UTV's, Sandrails and Buggy's.
