When actually measured with a measuring tape, it was about 54cm in the short state and about 152cm when extended. The top part can be removed by pressing the white button, and can be attached in the reverse way. It seems that the pole can be used for other light bulb sizes if you change the top part. It's quite old and has a lot of scratches and dirt. I have never actually used it, so I don't know how it works, please understand. It will be shipped by Yu-Yu Mercari Bin or Raku-Raku Mercari Bin in a cardboard box processed with bubble wrap and newspaper (on weekends and holidays, items shipped by Yu-Yu Mercari Bin will be changed to Raku-Raku Mercari Bin, please understand). I would appreciate it if you could read the profile before considering purchasing. I do not negotiate discounts. I look forward to your purchase. Thank you for reading to the end. #Matsushita Electric #Lamp Changer #Light Bulb Changer #Lamp Changer Pole #Lamp Changer Holder
