the lengths of the packing material a
min. of 1/4 in. to be butted together.
B. CERTIFIED MANUFACTURER: Hilti,
Inc.
CERTIFIED PRODUCT: Joint Spray or
Sealant
MODEL: Firestop Joint SprayCFS-SP
WB or Silicone Joint Spray CFS-SP SIL
Fill, Void or Cavity Material: Spray or
brush apply in two locations: (1) over
the interface of the inside vertical leg
of the of the floor track (Item 2B) and
the concrete floor assembly (Item 1)
and (2) over the interface of the
outside vertical leg of the floor track
(Item 2B) and the inside face of the
sandwiched wall surface (Item 2D).
Fill, Void or Cavity material is not
required behind the vertical studs.
Application of the material is to start
and stop on each side of each
vertical stud. When alternate box sill
is used, spray or brush apply liquid in
two locations: (1) over the interface
of the inside vertical face of the of the
box sill (Item 2B) and the concrete
floor assembly (Item 1) and (2) over
the interface of the top of the box sill
(Item 2B) and the inside face of the
sandwiched wall surface (Item 2D).
Apply at the thickness specified in
Table 1 and overlap the material a
min. 1/2 in. onto the adjacent curtain
wall assembly and concrete floor
slab assembly. When the brushing
or spraying process is stopped and
the applied liquid cures to an
elastomeric film before application
process is restarted, then overlap the
edge of the cured material at least
1/8 in. with the fresh material.
C. Reinforcing Angle: Mount a min. 20
GA, 1-1/2 in. x 3/4 in. galvanized
steel angle continuously to the top of
the slip-track (deflection channel)
(Item 2C) using min. # 6 x 1/2"
framing screws with pan or hex head
nominally 24 in. oc. Screws heads
located on bottom of slip-track
Position the reinforcing angle so that
the 3/4 in. horizontal leg attaches
the exposed top of the cantilevered
slip-track (deflection channel) (Item
2C) and the 1-1/2 in. vertical leg is
plumb with outside cantilevered
edge of the floor track (Item 2B)
above. Alternate: Mirror location
from above mounting. Mount a min.
20 GA, 1-1/2 in. x 3/4 in.
galvanized steel angle continuously
to the bottom track (Item 2B) using
min. #6 x 1.25 in. pan or hex head
head SD PT screws nominally 24 in.
oc. Position the reinforcing angle so
that the 3/4 in. horizontal leg
attaches the exposed bottom of the
cantilevered bottom track (Item 2B)
and the 1-1/2 in. vertical leg is
plumb with outside cantilevered slip-
track (deflection channel) (Item 2C)
below.
D. Steel Cover and Base: (Not shown)
Use nominal 6 in. by 2 in., 16 GA
steel "C" channel, bottom track (Item
2B), to cover the packing material
(Item 3A) and use nominal 6 in. by 2
in., 16 GA steel "C" channel, slip-
track (deflection channel) (Item 2C),
to support the packing material (Item
3A).
E. Optional Impaling Pins: (Not shown)
When desired, use 12 GA steel pins
swaged to nominal 2 x 2 in.
galvanized steel base plate affixed
max. 16 in. oc to edge of concrete
floor assembly (Item 1).
