Generated explanation

A cross section shows an automatic sectional garage door and ceiling-mounted opener beneath the floor framing of a house. The opener rail and connecting arm operate the door along its curved track, and a downward arrow indicates closing travel. A 2-inch block is positioned on the garage floor beneath the midpoint of the door to test contact-triggered automatic reversal. The annotations state that the door should stop after hitting the block and then reverse to the fully open position; they also note that some people substitute a roll of toilet paper or paper towel. No failed reversal or damaged component is depicted.
