CONNECT DOOR ARM - ONE PIECE DOORS
ONE-PIECE DOOR INSTALLATION:
Fasten the straight (1) and curved (2) door arm sections together to the longest possible length (with a 2 or 3 hole overlap) using
hardware (3,4 and 5). With the door closed connect the straight door arm section (1) to the door bracket with clevis pin (6).
Secure with ring fastener (7). Disconnect the inner and outer trolley. Slide the outer trolley back toward the opener and join the
curved arm (2) to the connector hole in the trolley (8) with clevis pin (6). It may be necessary to lift the door slightly to make the
connection. Secure with ring fastener (7).
NOTE: When setting the up limit, the door should not have a “backward” slant when fully open. A slight backward slant
(9) will cause unnecessary bucking and/or jerking operation as the door is being opened or closed from the fully open
position.
