Attach The Rail To The Header Bracket - Craftsman 139.53914 Owner's Manual

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'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"xl-1/2" as shown.
Insert a ring fastener to secure.
