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 ® 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.
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 ensure each borehole is drilled to the
proper depth and aligned with the part to be anchored per Anchoring Information table.

3) Clean the Boreholes
Blow the concrete dust from the borehole using oil-free compressed air. Thoroughly brush it
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.
