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" x 1-1/2" clevis pin as shown.
• Insert a ring fastener to secure.
