Call Toll Free - 1 888 305-3331 Mast Options Single, double, triple, quad (reflects the number of sections or stages the mast has) these are the types of masts available . In many circumstances you will not need to make a choice here since the lift height will dictate the type of mast you will get, however, in trucks with very high lift heights you may have an option. Going to a quad mast instead of a triple, rated at the same height, will give you a shorter mast in the lowered position, eliminating overhead clearance issues. Copyright 2011 Lift North America
