INSTALLATION STEP 3
Attachthe Rail to the HeaderBracket
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 eachside 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.
