Tracks have added grooves to accommodate retaining clips used with CB (captive ball) cars. Old style
non-CB cars also fit CB style track.
Cutting Track to Length Using Fastener Hole for Securing End Control
R27 tracks have holes drilled for E27 series stop and end controls
if entire length is used. If you shorten one end, make cut so end
control screw passes through a track fastening hole. It is best to
have track cut with an electric cross cut saw at a machine shop.
Low beam track may be cut using a hacksaw but it is difficult to
get a straight, even cut. Measure from center of hole to end of
track so hole center is

" (14 mm) from track end. If this does
not work, make sure that end control screw hole does not inter-
fere with mounting or pinstop hole. Note: Since trim caps are not
used with E32 or E27 end controls, do not leave room for them.

Installing Loader Track for Cockpit Installations
Track mounted in cockpit can make it impossible to remove
car without removing the entire track. Plan ahead to avoid
this problem. Cut a "loader track" section under one end
control. Loader track length must be long enough to slide
car off end. Measure track from finished end so that the 2nd
track fastener hole becomes the end control mounting hole
depending on whether short or long cars are used. Butt anodized track ends against each other so that
main and loader track align properly. Note: Loader track is required at only one end.
To slide the end control and car off the track, remove this section.
