3. Attach upper mount (to wood framing channels)

When cutting the wood framing channels, be sure the holes on each end will line up with the holes on the mounting
brackets!
Loosely attach the extension tube to the upper mount to determine where on the channels the mount should be attached. Fasten the
mount to the wood framing channels using the Mounting Hardware as shown. Tighten the Mounting Hardware to 25 ft·lb (33.9 N·m)
using a torque wrench with a 17 mm socket.
Measure the distance between the mounting brackets (bolt head to bolt head) so that the wood framing channels have enough
clearance in between the brackets. Cut both wood framing channels to the measured length.
