Use only Trinity Highway parts
that are specified herein for the
CAT®
for
assembling,
maintaining, or repairing the
CAT®. Do not utilize or otherwise
commingle parts from other
systems even if those systems
are Trinity Highway systems.
WARNINGS
Ensure that the post is installed per the above drawing with the three
(3) holes at the top of the post.
NOTE: When CAT® is assembled in a median, bolt
(Part CC) can be assembled from either side of the
tube sleeve. When CAT® is assembled on the
roadside, it is recommended the bolt be assembled
from the embankment side.
