EntelliGuard ACB, which runs across the width of the Retrofill EntelliGuard ACB.
5.
Align the three holes on the face of the supplied secondary block to the three holes on the plate and
secure the block to the plates using the ¼-20 thread forming screws. The screw tightening torque should
be ~40 in-lbs. (Be careful not to break the plastic).
