illustration as you proceed with the installation of your
garage door operator and The Chamberlain Arm™. The
garage door opener must be installed parallel to the floor.

Follow rail assembly instructions as shown in the Owner's
manual. Note: For the best operating result of canopy doors,
use only 3-sections of the 4-piece rail or add a rail support
bracket as shown (16). Make sure rail support bracket does
