I bought a special socket that fits from internet,socket jenie $30.00 and a low speed high torque drill from harbor freight $49 on sale for $39. Works great but you must play with torque settings to get correct speed. Very important to manually raise roof fully, mark a line on lifting bar that you can see while raising roof, crank roof down 6 to 8 turns, mark another line as a warning you are getting close to max height so you do not strip cable. Works great and is a fast roof raise.
