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 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.
