INSTALLATION STEP 3

Attach the Rail to the Header Bracket

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.
