Bolt channels to support structure.
5. First attach the retainers to the channel above the hole where the tubes pass
through the ceiling and where the channel can be supported. Retainers fit in the
Channel facing each other.
6. Bolt on the retainers loosely where needed, and then tighten securely “after
attaching and tightening the tubes”, #3 hardware. This is to ensure that the tubes
are flush on the retainers.
7. Drill 1/8 x 1 inch deep holes in the structure to attach the Channels.
8. Install the washer isolators with the bolts.
Note:
Fasten and tighten to supports well using #2 hardware and the washer
Isolators. Secure them well.
Thunder Mounting: Above the ceiling continued.
7a. Place the chrome ring through the tube glue it to the ceiling
After attaching the tubes. (Glue not included, contact cement works best)
You might need two people to do this next step. Or use a ladder to support the
Opener or a block on the garage door.
