System Overview
The QuadGuard
®
M10 is a re-directive, non-gating crash cushion for roadside features of
24” [610 mm] or greater in width with use of approved transitions. It consists of energy-absorbing
cartridges surrounded by a framework of Quad-Beam Fender Panels.
Important: Valtir 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
®
M10 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
®
M10 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.
The three (3) Bay QuadGuard
®
M10 has successfully passed the requirements stipulated in
MASH with both the light car and pickup trucks at speeds of up to 44 mph [70 kph] at redirection
angles up to 25 degrees.
During head-on impact testing, within MASH criteria, the QuadGuard
®
M10 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
®
M10 and delineation
used meet all federal, state, specifying agency, and local specifications.
