This tool automatically factors in a multiplicative factor of 1.2 in the load requirements as a minimum safety factor (actuators should not be run at 100% their maximum rated load).
Defaults to a recommended two actuators (one mounted on either side of the hatch), for added stability. Never push a hatch open from just one side. Option available to select one actuator but requires mounting in center of hatch.

Required force exceeds maximum rated load for this type of actuator. Please select a different mounting position and/or actuator.
