This is an Edelkrone Slider Plus+ V2 in very good condition. The medium version has a range of about 11" of travel on a table top to about 23" when mounted on a tripod. It has seen only very careful use and is in excellent condition. Very high quality well constructed slider with adjustable feet. Comes with original box. Thanks for looking.
