Limitations and Warnings
Pursuant to MASH “Recommended Procedures for the Safety Performance of Highway Safety
Features”, Trinity Highway contracts with FHWA approved testing facilities to perform and
evaluate crash tests to prepare a crash test results report. Trinity Highway is then able to submit
a Request for Federal Aid Reimbursement of Safety Hardware Devices to the FHWA for review.
These AASHTO directed tests are not intended to represent the performance of systems
when impacted by every vehicle type or every impact condition existing on the roadway.
This system is tested only to the test matrix criteria of MASH as approved by FHWA.
Trinity Highway expressly disclaims any warranty or liability for injury or damage to persons or
property resulting from any impact, collision or harmful contact with products, other vehicles, or
nearby hazards or objects by any vehicle, object or person, whether or not the products were
assembled in consultation with Trinity Highway or by third parties.
The QuadGuard®M Wide is intended to be assembled, delineated, and maintained within specific
state and federal guidelines. It is important for the highway authority specifying the use of a
highway product to select the most appropriate product configuration for site specifications. The
customer should be careful to properly select, assemble, and maintain the product. Careful
evaluation of site layout, traffic speed/type, direction, and visibility are some of the elements that
require evaluation by the highway authority in the selection of a highway product. For example,
curbs could cause an untested effect on an impacting vehicle.
After an impact occurs, the debris from the impact should be removed from the area immediately
and the specified highway product should be evaluated and restored to its original specified
condition or replaced as the highway authority determines as soon as possible.
Warning: Do not assemble, maintain, or repair the QuadGuard®M Wide until you
have read this manual thoroughly and completely understand it. Please contact
Trinity Highway if you do not understand these instructions (p. 3).
Warning: It is the responsibility of the installer to ensure that all Danger, Warning,
Caution, and Important statements within the QuadGuard®M Wide manual are
completely followed. Failure to follow this warning could result in serious injury or
death in the event of a collision.
The QuadGuard®M Wide has been deemed eligible by FHWA as meeting the requirements and
guidelines of MASH. These tests evaluate product performance defined by AASHTO involving
lightweight cars (approx. 1100kg [2420 lb.]) and full size pickup trucks (approx. 2270kg [5000
lb.]). A product can be certified for multiple Test Levels. The QuadGuard®M Wide is certified to
the Test Level(s) as shown below:
Test Level 3: 100 kph
ingalcivil.com.au 5 Revision B April 2021

System Overview
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
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.
Inspect Shipping
Check the received parts against the shipping list supplied with the system before deploying the
QuadGuard®M Wide. Make sure all parts have been received (pp. 40 - 41).
Important: The Manufacturer’s Drawing Package supplied with the QuadGuard®
M Wide must be used with these instructions for proper assembly and should take

ingalcivil.com.au 14 Revision B April 2021

Site Preparation/Foundation
AQuadGuard®M Wide, for permanent applications, should be assembled on anexisting or freshly
placed and cured concrete base (28 MPa [4000 psi] minimum). Location and orientation of the
concrete base and attenuator must comply with project plans or as otherwise determined by the
local highway authority.
Recommended dimension and reinforcement specifications for new concrete foundations are
provided in Trinity Highway concrete foundation drawings, supplied with the system. The system
may also be assembled on reinforced or non-reinforced concrete roadway (minimum 200 mm
thick). Deployment cross-slope shall not exceed 8% and should not twist more than 2% over the
length of the system; the foundation surface shall have a light broom finish.
Warning: It is the responsibility of the installer to ensure proper site grading for
the QuadGuard®M Wide placement as dictated by the state or specifying agency
pursuant to the AASHTO Roadside Design Guide.
Caution: Accurate placement of all steel rebar is critical to avoid interference with
the concrete anchor bolts.
Warning: Location of the Backup in relation to nearby objects will affect the
operation of the attenuator. Upon impact, the Fender Panels telescope
rearward and extend beyond the rigid Backup as much as 762 mm. Position the
Backup so that the rear ends of the last Fender Panels are a minimum of 762
mm forward of objects that would otherwise interfere with movement of the
rearmost Fender Panels. Failure to comply with this requirement is likely to result
in system performance which has not been crash tested pursuant to MASH
criteria and may also cause component damage which will necessitate
maintenance or replacement of the system.
Important: QuadGuard®M Wide cannot be mounted on asphalt.

Trinity Highway Approved Adhesive Anchoring System
A Trinity Highway approved adhesive anchoring system is required to securely anchor crash
cushions. Each approved adhesive kit contains adhesive, studs, nuts and washers. Both vertical
and horizontal assemblies are possible using an approved adhesive anchoring system.
Vertical Anchors
Note: Read all Trinity Highway approved adhesive instructions before starting.
1) Prepare the Concrete Foundation
Warning: Do not allow anchoring adhesive to contact skin or eyes. See material
safety data sheet supplied with adhesive kit for first-aid procedures. Use only in
well-ventilated area. Do not use near open flame.
Warning: It is the responsibility of the installer to maintain a safe work area
including the use of standard work zone safety equipment & PPE: gloves, safety-
toe shoes, and eye / ear protection.
2) Drill Boreholes
Use the Monorail(s) and Tension Strut Backup as drilling templates. Use a rotary hammer drill
to drill the boreholes 22 mm diameter to the recommended depth. See the approved
adhesive instructions provided with adhesive kit. Check ensure each borehole is drilled to the
proper depth and aligned with the part to be anchored per Anchoring Information table.

Vertical
22 mm 180mm
ingalcivil.com.au 17 Revision B April 2021
The anchor bolts (studs) that anchor the QuadGuard®M Wide Backup and/or Monorail
sections to the concrete foundation must be those shipped in the kit or of high strength steel
(120,000 psi [830 MPa] minimum tensile strength or equal). These studs must be set in
minimum 4000 psi [28 MPa] concrete. Allow the concrete to cure a minimum of seven days
before applying anchoring adhesive.
Caution: It is the responsibility of the installer to consult Safe Work
Australia, Worksafe NZ, or state & territories for debris removal from
borehole(s) and use Trinity Highway approved adhesive to achieve
optimum tensile strength. Do not use diamond drill bits for drilling
boreholes.

4) Apply Approved Adhesive
Fill the borehole 100% full.
Caution: Fill borehole 100% full so it is even with the pavement surface per
manufacturer’s instructions.
5) Add the Washers and Nuts
Place a flat washer onto the stud then thread a nut on until the end of
the stud is flush with the nut (Figure 8).
6) Insert Studs in Boreholes and Wait for Adhesive to Cure
Push the stud down through the part to be anchored and into the
borehole.
Caution: Do not disturb or load the stud until the approved
adhesive material has fully cured (reference instructions
supplied with the approved adhesive kit).
7) Torque the Nuts
Once the adhesive has fully cured, torque the nut to the adhesive
manufacturer’s recommended values.
Anchor Assembly Cautions
1) Steel rebar
If steel rebar is encountered while drilling an anchor bolt borehole, apply one of the following
solutions:
A) Use a rebar drill bit for the rebar only and then switch back to the concrete bit to finish
drilling into the underlying concrete until the proper borehole depth is reached.
Caution: Do not drill through rebar without first obtaining permission to do so
from the project engineer.
B) Drill a new borehole down at an angle past the rebar to the proper depth. Anchor the
stud by completely filling both boreholes with an approved adhesive.
