Hilti Retrofit addition CP 680 110/4” N-RAD : Installation Guidelines:
Document Reference : RAD Installation Tips, March 2014 : Page 1 of 3
Step 1: Place to Install:
Place the RAD with the Red
surface facing the bottom of
the installed Hilti Fire
Collar.
You only need 30mm
clearance from the bottom
of the slab to do this, and
more space is even better.
Step 2: Rotate to Install:
Leverage the RAD so that
the Red surface becomes
visible from the bottom of
the collar.
Even with only 30mm
clearance from the bottom
of the slab you can do this.
With more space it is very
easy to do this.
Step 3: Push to Install:
Push the RAD so that the
Red surface becomes
100% visible from the
bottom of the collar.
The RAD will fit tightly into
the bottom of a Hilti Fire
Collar, and hold in place for
the screws to be inserted
into the pre-drilled holes.
