INSTALLATION STEP 3
Attach the Rail to the Header
Bracket
NOTE: (Optional) With an existing Craftsman
installation, 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 front rail end within the header bracket
and join with a 5/16"x1-1/2" clevis pin as shown.
Insert a ring fastener to secure.
