Slide the Control Head onto the jackshaft and select a hole on the
bearing plate or door frame for the torque arm.

If no
hole is available then drill a 1/4” hole in a suitable location. Bolt the
torque arm to the bearing plate or door frame and secure the other
end to the torque arm fixing the hole on the Control Head, use the
supplied spacer if the offset is not enough to clear the drum. (

THE BUTLER kit
includes an anti-rotation torque arm; it is possible to mount the Control Head inboard or outboard
the bearing plates and
horizontally
or
vertically
so long as the torque arm is at right angles to the operator. This
stops the operator from moving side to side when the door is moving.
