This adapter is assembled onto the Tier 4 Exhauster Blower and lifted with a T85681LA Lift Arm (not included) attached to a T57170 "C" Frame. The stem is inserted into the angle iron on the side of the blower and threaded into the bottom plate to secure. The T85681LA Arm cradles the ball portion of the bolt and lifts the blower by raising the "C" Frame.
the second picture below is our certification fixture, but it shows the appliance assembled onto the T4 Exhauster Blower.
