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"x1-1/2"
as shown.
• Insert a ring fastener to secure.
