INSTALLATION STEP 3

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.
