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.
