same way, using the 5/16"x1-1/4" clevis pin.
• Figure 2:

that line up and join sections. If possible, use the
top and bottom holes on the curved door arm, as
shown.
• Figure 3, Hole Alignment Alternative:

arm, disconnect straight arm. Cut about 6" from the
solid end. Reconnect to trolley with cut end down
as shown.

screws, lock washers and nuts.
