the lock washer and nuts as shown.
• As a temporary stop, insert a screwdriver into the
hole in the front end of the T-rail.

ASSEMBLY STEP 3
Fasten the T-Rail to the Motor Unit
• Place the opener on packing material to protect
the cover. For convenience, put a support under
the cable pulley bracket.

mounted in the top of the motor unit.
• Align the holes in the back section of the T-rail with
the holes in the motor unit.
• Fasten the rail with the two washered bolts
previously removed. Tighten securely. Remember
to use only these bolts! Any other bolts will
cause serious damage to the opener.
• Insert a 5/16"-18x7/8" hex bolt into the cover
protection bolt hole in the T-rail as shown. Tighten
securely with a 5/16" lock washer and nut.

2" minimum between the trolley and this bolt when
adjusting travel limits (see page 28).
