The TRI70 Tripod collapses to 18" and includes a nylon storage bag with handle for transport. When open, working height can be adjusted between 16" and 45". The top of the tripod has round flat surface that measures 2-3/8" across with a male 1/4-20 mount extending 1/4" high. The TRI70 legs and body are made from aluminum. Each leg is three sections with a positive lock mechanism and there is a circular bubble vial to assist in leveling the unit. It is designed to be a sturdy and stable base for the Leica DISTO FTA360, FTA360S, TA360 adapters and Leica Lino line and point lasers. This tripod could easily be used for most any camera, video camera, or web cam applications where a flat mounting surface is desired
