The Trac system must be mounted using the appropriate
fasteners in the pre-drilled mounting holes as follows:
• 4==B;;(@/1— two places, one at each end of
Trac.
• 4==B;;(@/1— three places, one in the center
and one in each end of the Trac.
• 4==B;;(@/1— four places, one at each end
of Trac and one four feet from each end.
If Trac requires field cutting, refer to the “Cutting Trac to Special
Lengths” procedure. If Trac does not require field cutting,
proceed to “Installing the Trac.”
CBB7<5(@/1B='>317/: 3<5B6A
NOTE: Cutting should be done from the dead end of the Trac.
1. Remove the dead end fitting and push the copper buss
bars and insulators flush with the live end of the Trac.
Measure length from the live end and mark the cut line.
2. Using a hacksaw, cut to desired length. Be sure to allow
1/8" (3 mm) for dead end fitting which must be reinstalled
to the Trac end.
3. Remove all burrs from the Trac, insulators, and copper
buss bars.
4. Push the copper buss bars into the insulators 1/2" (13 mm)
from the end of the Trac.
NOTE: After completing the above step, the buss bar
insulators should be flush with the Trac channel ends,
and the copper buss bars should be cut back from
each end of the Trac a minimum of 7/16" (11 mm) to a
maximum of 1/2" (13 mm). If this is not the case, make
appropriate modifications.
5. Reinstall the dead end fitting and tighten the screw.
If additional mounting openings are required, follow
this procedure in drilling holes:
1. Locate desired mounting holes on the inside center line of
the Trac section.
2. Drill a 3/16" hole through the Trac channel.

After Trac has been field cut, make sure that each 4’ (1219
mm) section or less in length has one mounting hole spaced
a maximum of 6" (152 mm) from each Trac end section. A
single section of Trac that is greater than 4' (1219 mm) in
length must have the mounting hole located a maximum of
12" (305 mm) from each end of the Trac with additional
mounting holes located a minimum of every 4' (1219 mm)
along the length of the Trac section. Additional mounting holes
may be drilled as needed.
Live End Fitting
Dead End Fitting
(To remove,
loosen screw and
slide out fitting.)
Drill mounting holes
where required.
Measure the desired length from the live end.
NOTE: The dead end fitting will add 1/8″ to this length.
New cut must be at an
exact right angle (90°).
