Position opener on garage floor below the header bracket. Use
packing material to protect the cover. Raise rail until holes in the
header sleeve and holes in the header bracket align. Join with
clevis pins (1). Insert ring fasteners (2) to secure.
NOTE:
To enable the rail to clear sectional door springs, it may
be necessary to lift opener onto a temporary support. The
opener must either be secured to a support or held firmly in
place by another person.

A 25mm board (1) is convenient for setting an ideal

laid flat on the top section of door near the
centreline as shown. Rest the rail on the board.
If the raised door hits the trolley, pull down on the trolley release
arm to disconnect the trolley from the chain. The trolley can
