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.
