This was our original design and the oldest and most popular of our devices
until it was overtaken by the 1 inch 16:1.
It is 3/4 inch input and 1 inch output.
Maximum output is 2500 ft./lbs. or 2000 Nm.
It utilizes a planetary gear drive to produce a gear ratio of 4:1.
The best measurement of the torque ratio across the full operating spectrum is 3.3:1.
This is similar in appearance and shares many parts with our 16:1 multiplier with 1 inch drive.
