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.
The QuadGuard®Elite M10 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. 2420 lb. [1100 kg]) and full size pickup trucks (approx. 5000
lb. [2270 kg]). A product can be certified for multiple Test Levels. The QuadGuard®Elite M10 is
certified to the Test Level(s) as shown below:
Test Level 3: 62 mph [100 kph]
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

System Overview
The QuadGuard®Elite M10 is a potentially reusable, re-directive, non-gating crash cushion for
roadside features of 24” [610 mm]. It consists of energy-absorbing high density polyethylene
cylinders surrounded by a framework of Quad-Beam Panels.
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®Elite M10 system utilizes two types of Cylinders 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 8Bay QuadGuard®Elite M10 systems have successfully passed the requirements stipulated
in MASH, Test Level 3 tests with both the light car and pickup trucks at speeds of up to 62 mph
[100 kph] at angles up to 25 degrees.
During head-on impact testing, within MASH criteria, the QuadGuard®Elite 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®Elite M10 and delineation
used meet all federal, state, specifying agency, and local specifications.

TrinityHighway.com 13 Revision B October 2019
Site Preparation/Foundation
A QuadGuard®Elite M10 should be assembled only on an existing or freshly placed and cured
concrete foundation (4000 psi [28 MPa] minimum). Location and orientation of the concrete base
and attenuator must comply with project plans or as otherwise determined by the resident project
engineer.
Recommended dimension and reinforcement specifications for new concrete foundations are
provided in Trinity Highway Concrete Foundation drawing, supplied with the system. The system
may only be assembled on reinforced concrete roadway (minimum 6” [150 mm] thick). Assembly
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.
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 25” [635 mm]. Position the Backup
so that the rear ends of the last Fender Panels are a minimum of 25” [635 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.
Warning: Ensure that there is proper site grading for the QuadGuard®Elite M10
placement as dictated by the state or specifying agency pursuant to the AASHTO
Roadside Design Guide.

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.
The anchor bolts (studs) that anchor the QuadGuard®Elite M10 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.
2) Drill Boreholes
Caution: It is the responsibility of the installer to consult OSHA silica
respiratory standard 29 CFR 1910.134 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.
Use the Monorail(s) and Tension Strut Backup as drilling templates. Use a rotary hammer drill
to drill the boreholes 7/8” [22 mm] diameter to the recommended depth. See the approved
adhesive instructions provided with adhesive kit. Check to ensure each borehole is drilled to
the proper depth and aligned with the part to be anchored per Anchoring Information table.
Anchor Information
Stud Size: Orientation Bit Size Minimum Depth Torque Medium
3/4” X 6 1/2" Horizontal 22 mm [7/8”] 125 mm [5”] Manufacturer Spec Concrete
3/4” X 7" Vertical 22 mm [7/8”] 146 mm [5 3/4”] Manufacturer Spec Concrete
3) Clean the Boreholes
Blow the concrete dust from the borehole using (90 psi) oil-free compressed air. Thoroughly
brush the borehole with a 7/8” diameter steel bristle tube brush and then blow it out again. If
the borehole is wet, completely flush it with water while brushing and then blow it clean to
remove all water using oil-free compressed air.
Note: Use of the Trinity Highway approved vacuum drilling equipment is authorized to replace
the blowing and brushing requirement of Step 3.

TrinityHighway.com 16 Revision B October 2019
4) Apply Approved Adhesive
Fill the borehole 100% full.
Caution: Fill borehole 100% full so it is even with the pavement surface per the
adhesive 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 3).
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.
Warning: 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.
Figure 3
Anchor Application
(Before Applied Torque)

TrinityHighway.com 17 Revision B October 2019
Horizontal Anchors
The horizontal approved adhesive kit is the same as the vertical kit.
Caution: Fill borehole 100% full so it is even with the vertical concrete surface
per manufacturer’s instructions.
1) Follow the instructions supplied with your approved adhesive kit
Apply approved adhesive to each anchor per instructions.
2) Add the Washers and Nuts
Put washer and nut on stud so the nut is flush with end of stud.
3) Insert each Stud with Washer and Nut into Borehole
Push stud with washer and nut into borehole.
Important: The stud should be flush with the top of the nut in both vertical and
horizontal applications prior to tightening (Figure 4).
Caution: Do not disturb or load the stud until the approved adhesive material has
hardened (reference approved adhesive kit instructions for hardening times).
4) Torque the nuts
Once the adhesive has fully cured, torque nut(s) to the approved adhesive manufacturers
specification.
