Can you add this American DJ LTS-50T-IBEAM 5ft Extension for LTS-50 to make the unit 15 ft?
Yes you can. 15' would be the max and the amount of weight it canhandle reduces by 100lbs.
how can I get the parts the expand my LTS50T to 15'
Attached is the parts site for the Lts-50T. Please remember we do not reccomend anything past 15' http://parts.adj.com/ProductsList.aspx?ProductLine=0073&ProductDesc=LTS-50T
