ASSEMBLY STEP 2

Install the Trolley

• As a temporary stop, insert a screwdriver into the
hole in the front end of the T-rail.
• Slide the trolley assembly along the rail to the
screwdriver stop. NOTE: If trolley hits against any
nuts on the T-rail, the bolts and nuts were attached
from the wrong side and must be repositioned.
Review Assembly Step 1.
• Insert a 5/16"-18x7/8" hex screw into the trolley
stop hole in the T-rail as shown. Tighten securely
with a 5/16" lock washer and nut. This screw limits
trolley travel in the DOWN direction.

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 screws
previously removed. Tighten securely. Remember
to use only these screws! Any other screws
will cause serious damage to the opener.
• Insert a 5/16"-18x7/8" hex screw into the cover
protection bolt hole in the T-rail as shown. Tighten
securely with a 5/16" lock washer and nut.
