 Support operator head slightly off the floor.
 Lift the opposite end of the rail up to the header bracket.
 Position rail end-stop within the openings in the header
bracket. Insert header clevis pin ( 1/4” dia.) through header
bracket and rail end, then attach cotter ring to end
of pin. (See Fig. 19A)
8-7. POSITION OPERATOR FOR MOUNTING
Once rail is attached to header bracket, support operator on ladder
or use the assistance of another person to hold operator high
enough so door can open without hitting the rail.
Open garage door to fully opened position, and place a 2x4
(50mm x 100mm) laid flat between the door and the rail.
See Fig. 20. This provides an easy method of ensuring the
correct mounting height of the opener.
