CONNECTING DOOR ARM ONE PIECE DOORS
Assemble the Door Arm:
• Fasten the straight and curved door arm
sections together to the longest possible
length (with a 2 or 3 hole overlap) (Figure 4).
• Make sure the garage door is fully closed.
Connect the straight door arm section to the
door bracket with the clevis pin.
• Secure with a ring fastener.
• Pull the emergency release handle disengage
the trolley by pulling straight down on the
emergency release cord. Slide the trolley
toward opener.
• Connect the curved arm section to the trolley
using the clevis pin and ring provided.
NOTE: When setting the up limits, the door

backward slant will cause unnecessary
buckling and/or jerking operation as the door
is being opened or closed from the fully open
position (figure 5).
