STEP 1: Mounting the Front Bracket — Sectional Doors and One-
Piece Doors with Track (For One-Piece Doors without track see Step 1A,
next): Mark a vertical centerline on the header above the door. By
manually raising the door, determine the high arc of the door’s travel (see
illustration, top of previous page) and using a level, transfer this
measurement to the header (see illustration at left). Draw a horizontal line,
crossing the previously drawn centerline, at this point. Install the Front
Mounting Bracket securely wit lag screws as shown below. If necessary,
reinforce the header with steel angle iron or wood to ensure a secure
mount.
