The back rail has a similar hole close to the edge, about 4-3/4" from the far end. A 3-piece rail uses two back rails.
Assembly Step 2 Fasten the Rail to the Opener • Insert a 1/4"-20xl-3/4 bolt into the cover protectionbolt hole on the back end of the railas shown. Tighten securely with a 1/4"-20 lock nut. • Remove the two screws from the top of the opener. • Attach spreaders to the U bracket by snapping them into place. • Place the U bracket, flat side down, on the opener and align the bracket holes with the screw holes. Fasten with the previously removed screws.
