This is a replacement column, identical to the ones that come with the Master C-Stands with Turtle Base. It features a junior 1-1/8" mounting pin in the bottom and a steel baby mounting pin on the top. They are an economical way of changing your stand height without the necessity of buying an additional stand complete with base. It weighs 10.4lbs (4.7Kg) and is 8.9' (2.7M) when fully extended.
