The MP-3 Polyester Anchoring System is a quick and
easy way to securely anchor crash cushions and other
common highway devices. MP-3 features high pullout
strength, superior vibration resistance, and exceptional
durability.
Each MP-3 kit contains a can of MP-3 resin, hardener, cold
weather promotor, studs, washers, nuts and a complete
safety sheet. The cold weather promoter shortens harden-
ing time by as much as seven hours. Both vertical and hori-
zontal installations are possible using the MP-3 System.
WARNING!
Wear safety goggles and gloves during installation.
MP-3 Anchoring Information
WARNING!
Do not allow the MP-3 Resin or Hardener to contact
skin or eyes. See material safety data sheet supplied
with the MP-3 kit for first-aid procedures. Use only in
well-ventilated area. Do not use near open flame.

Note: Read MP-3 Instructions before starting.
1) Prepare the concrete pad
The anchor bolts (Studs) that anchor the
QuadGuard
cz to the concrete pad must be those
shipped in the kit or of high strength steel (830 MPa
[120,000 psi] minimum tensile strength or equal.)
These Studs must be set in minimum 28 MPa
[4000 psi] concrete. Allow the concrete to cure a
minimum of 7 days before installing MP-3.
2) Drill holes
Note: Energy Absorption Systems recommends us-
ing two fluted drills to achieve optimum tensile
strength when installing the MP-3 anchoring system.
Use the part that is to be anchored as a drilling tem-
plate. Drill the holes 3 mm [1/8"] larger than the stud
diameter to the recommended depth, using a rotary
percussive drill. Full strength will not be achieved if a
diamond drill is used. Refer to the MP-3 installation
instructions provided with your kit. Check to be sure
all the holes are drilled to the proper depth and aligned
with the part to be anchored. Refer to
Table
A.

WARNING!
Do not use Promoter when the temperature is above
15 degrees Celsius (60 degrees Fahrenheit). Grout will
harden too quickly.
3) Clean the holes
Blow the concrete dust from the hole, using oil-free
compressed air. Thoroughly brush it with a stiff-
bristled brush, and then blow it out again. If the hole
is wet, completely flush it with water while brushing.
Then blow it clean, using oil-free compressed air.
4) Mix the resin and hardener
Wearing gloves and safety goggles, remove the lids
from the MP-3 Part A-Resin and Part B-Hardener con-
tainers. Pour Part B into Part A, then mix vigorously
for 30 seconds to form MP-3 grout (an anchor stud
may serve as a stirring rod).
5) Add cold weather promotor (in cold weather)
For faster hardening in cold weather, Promoter may
be used. Add the entire contents of the partially filled
Promoter container to the MP-3 grout; then mix for
an additional 30 seconds. Use immediately because
the MP-3 grout will thicken quickly. Refer to
Table
B
for hardening times.
6) Pour grout into holes
