INSTALLATION STEP 3
Attach the Rail to the Header Bracket
• Position the opener on the garage fl oor below the
header bracket. Use packing material as a protective
base. NOTE: If the door spring is in the way, you will
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
as shown.
• Insert a ring fastener to secure.
