Attach the T-Rail to the Header
Bracket
1. 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.
2. Position the rail bracket against the header
bracket.
3. Align the bracket holes and join with a clevis pin
as shown.
4. Insert a ring fastener to secure.
