Ranges from 22" to 72" with center post extended. Center post is reversible for low work. Very solid, stable platform. A bit of surface corrosion on the nuts. This was put into use when I tested a wide variety of pods for Pentax 67 duty. This was the best at dealing with the P67 system for me. I also have used this with a monopod attached to hold monolights after an emergency had me resort to that solution and it worked so well that I did it on other occasions. It's big enough to straddle church pews and solidly hold lights. I used it with a 3040 Bogen head. I may be selling that, too so please inquire if you would like the package. Weighs about 7 pounds. $85 + shipping and I'll give $5 to APUG.
