Normally about five minutes. There are two bolts that need to be removed from each of the four legs for the T-Top to fold forward. Then two bolts are removed from each side of the top section to allow it to fold. Only one bolt is required for each location except when used in rough water or when over 20 lbs of accessories are attached to the top. For customers that need to more regularly put their T-Tops up and down a quick release knob kit is available.
