Use only Trinity Highway parts
that are specified herein for the
SRT™
31
System
for
assembling, maintaining, or
repairing the SRT™ 31 System.
Do not utilize or otherwise
commingle parts from other
systems even if those systems
are Trinity Highway systems.
WARNINGS
Do not attach the SRT™-3 Guardrail to post 5. Do not place anything
between the post bolt head and the SRT™ 31 Anchor Guardrail that
would prevent the bolt from pulling through (i.e. no rectangular washer
or delineator). Ensure the SRT™-3 Guardrail is straight between posts
7 and 5. Failure to follow this warning could result in serious injury or
death in the event of a vehicle impact with the system.
Do NOT alter the lap orientation of the
length-of-need guardrail when
assembling a downstream/trailing end
SRT™ 31 System.
