A gravel packing method and apparatus allows setting the packer by dropping a ball to a seat that it isolated from the effects of formation pressures when trying to set the packer. Such handles will prevent any down time by logging in the parts to be replaced by an operator when certain level of bit errors is reached. The folding spreader mechanism is prevented from extending over-center and locking like a knee joint as near the point of going over-center, a tiny force like a trigger keeps the folding spreader mechanism extended even against strong spring pressures.
