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 header/rail bracket against the header
bracket.
• Align the bracket holes and join with a clevis pin
5/16"x2-3/4" as shown. Spacer can be installed on
either side of rail.
• Insert a ring fastener to secure.
