System Overview
The QuadGuard ® M Wide is a re-directive, non-gating crash cushion for roadside features of
69” [1753 mm] or less in width with use of approved transitions. It consists of energy-absorbing

Quad-Beam Fender P anels.
Important:
Trinity Highway makes no recommendation whether use or
reuse of any part of the system is appropriate or acceptable following an
impact. It is the sole responsibility of the project engineer and/or the local
highway authority and its engineers to make that determination. It is critical
that you inspect this product after assembly is complete to make certain that
the instructions provided in this manual have been strictly followed.
The QuadGuard
®
M Wide utilizes two types of cartridges in a “staged” configuration that are
designed and tested to address vehicles as defined by MASH for both lighter cars and heavier,
high center-of-gravity vehicles.
Impact Performance
The six (6) Bay QuadGuard ® M Wide has successfully passed the requirements stipulated in
MASH with both the light car and pickup trucks at speeds of up to 62 mph [100 kph] at redirection
angles up to 25 degrees.
During head-on impact testing, within MASH criteria, the QuadGuard ® M Wide has been shown
to telescope rearward to absorb the energy of impact. When impacted from the side, within the
applicable MASH criteria, it has been shown to redirect the vehicle back toward its original travel
path and away from the highway feature.
Warning:
It is the sole responsibility of the project engineer and/or local highway
authority and its engineer to ensure that the QuadGuard ® M Wide and delineation
used meet all federal, state, specifying agency, and local specifications.
Warning:
