Attach the Rail to the Header Bracket

NOTE: (Optional) With some existing installations, you may
re-use the old header bracket with the two plastic spacers
included in the hardware bag. Place the spacers inside the bracket
on each side of the rail, as illustrated.
• Position the opener on the garage floor below the header
bracket. Use packing material as a protective base.
NOTE: If the door spring is in the way you'll need help. Have
someone hold the opener securely on a temporary support to
allow the rail to clear the spring.
• Position the rail bracket against the header bracket.
• Align the bracket holes and join with a clevis pin 5/16"x1-1/2"
as shown.
• Insert a ring fastener to secure.
