Step 4: Drill to Install:
Screw the RAD so that it is
securely fixed into the metal
ring in the bottom of the
Hilti Fire Collar.
Use a Hex Head socket,
and a cordless screw-gun
with sufficient torque to drill
the screws into the metal
ring.
Step 5: Meet to Install:
Position the second half of
the RAD so that it meets,
but does not overlap, the
first half of the RAD.
Then repeat steps 1 – 4
above.
RAD install time should be
less than 2 minutes.
