Read Instructions Before You Cut or Mount Track
It might be necessary to put trim caps, control blocks, and traveler car on
track before mounting. Slide control assemblies onto track with bumper
facing car. Keep control assembly loose so it can be moved out of the way
while installing track.
To cut track to length, make sure stop holes for control blocks do not
interfere with hole for mounting track. If necessary, cut both ends of track.
To determine correct track length, make sure track ends, without trim caps,
are 19 mm ( / ") from edge of cockpit coaming.
