ProSet Systems, Inc. was the first
company to test a firestop device at Underwriters
Laboratories in accordance with U.L. #1479 and ASTM
E-814 fire test standards. The tests were conducted in
May of 1982 making ProSet the most experienced provider
of unique firestop sleeve devices.
ProSet’s complete line of
“Firestop Penetrations” equals or surpasses all of the
current building and life safety codes. In addition to
being fire rated, when our “Penetrations” are set in the concrete pour,
they are highly water-resistant. Our
Guard sleeves are rigorously tested to be used when
the penetration must be waterproof.
Our Penetrators also allow pipe
expansion and contraction and reduce pipe noise.
ProSet firestopping is
accomplished by simply installing pipe, fittings and
hangers, and the fire ratings are completed at the same
time the pipe is installed! This contributes
significantly to improved scheduling and productivity
and allows the piping trades to take care of their own
fire rated penetrations.
ProSet has developed
three systems of firestopping: Systems “A”, “B” and
“C”. Each system is unique in the method it uses for
penetrating floor & wall construction assemblies.
See Below for a description of these three systems.

The ProSet Firestop
ProSet has a “Firestop
Manual” showing detailed drawings and installation
instructions which are in full compliance with Warnock
Hersey ASTM E-814 and Can S-115 third party fire
The manual has “Firestop
Penetrator Matrix Guides” listing common types of pipes and openings
passing through different fire rated floors and walls.
You can download the appropriate Matrix, based on
Construction Type, by clicking the corresponding button
under "Downloads" at the top left of this page.
You can access these Matrix Guides on our
Information page by clicking here.
The matrix guides you to the
desired detail drawing. The drawings include a complete
Warnock Hersey design number firestop assembly, showing
an exploded view with component parts and the Warnock
Hersey design listing number.
For Water, Electrical or
Other Pass-Through Piping Cast-In Place or Through Cored
“A” is used mainly for pressure-type piping such as
water, gas or electrical.
Blanks to 1½” pipes pass through
the plug & sleeve. The split ProSeal Plug driven into
the topside of the sleeve will complete the securing and
the firestopping of the pipe. That’s it! You’re done!
The same process is used with
pipes 2” through 10” except, instead of using the
ProSeal Plug, a ProSet Riser Clamp is used. The system
can be used with insulated pipe by using an intumescent
strip around the bottom of the sleeve.

For No-Hub Cast Iron DWV Pipe
Cast-In Place or
Through Cored Holes
“B” Penetrations are for cast iron. There are many
variations depending on how you want to connect the
piping to the sleeve couplings. Choices are usually
based upon pipe fabrications and ease of installation.
Whatever approach you use, ProSet has a specifically
designed penetration sleeve, eliminating the time and
nuisance of jury-rigging. Firestopping is accomplished
by simply connecting to the sleeve coupling or running
the pipe through the sleeve. The penetrations can be
used through floors or walls.
By using the ProSet
sleeves, the piping is much easier to install. All the
openings are connected at the same time you are piping
the system. There is no go-back work.
Provides a water, smoke
and fire resistant penetration � Secures the entire DWV
stack & branch piping � Has a “Fixed Point” fabrication
system � Allows an easy one-man installation � There is
no other firestopping required � Installs easily, costs
less, and produces a much better job.
Cast iron no-hub, copper
or steel DWV piping � All types of plumbing floor
System "C" Penetrations
Combustible Plastic and DWV Piping Cast-In Place or
Through Cored Holes
“C” Penetrators for combustible piping are fire
protected with a built-in intumescent wrap strip in the
bottom portion of the mounting flange.
The sleeve coupling extends up
from the mounting flange to fit flush with the
concrete. They can be used through floors and walls.
By using the ProSet
sleeves, the piping is much easier to install. As with
System “B”, all the openings are connected at the same
time you are piping the system. There is no go-back

Each ProSet penetration
opening supports the pipe and serves as a hanger.
Generally there are no hangers needed to support the
branch piping to the openings unless the length exceeds
the recommended spacing. Only then should an additional
hanger be required.
For System “B”, pass
through system, the ProSet Riser support is part of the
firestop system and eliminates the need for the
old-fashioned riser clamp.
For System “C”, each
solvent-cemented joint acts as a hanger. The Stack
is supported by using a solvent cement dauber to swab
around the pipe and the sleeve. This secures the pipe;
there is no need for a riser support.
When contractors break
down the cost of installing DWV piping in a building,
they realize that at least 75% of their time is used for
supporting and securing the piping system.
who know how to use the ProSet System enjoy savings of
about 50% on their labor costs.
Tub Box Opening
Shower and Hub Drain Openings
sleeve couplings can convert to water closet
openings by using a ProSeal closet flange with a
built-in elastomeric seal. This replaces the wax
ring, which can get distorted after a period of
time and leak sewer gas or water waste.
System “C” sleeve couplings (for plastic pipe)
can be converted to water closet openings
without using wrap strips.
need a firestop penetration of a fire-rated wall,
ProSet provides sleeves for concrete, block and gypsum
walls. Our wall penetrations come with the same quality as
our floor penetrations and have the same firestopping,
waterproofing and productivity benefits.
Bathtubs are connected using our tub box: a
rectangular box with a knockout in it for
testing purposes; and a sleeve coupling at the
bottom to connect the branch piping. For
System “C” (plastic piping), the sleeve coupling
does not require a wrap strip.
This provides a key benefit: the ability to
connect the branch pipe to the tub box coupling
while installing the rest of the piping.
There is no reason to return to connect the tub,
which saves time and money.
A Poke-Out Firestop Device
Hub-Seal Device is used when ABS or PVC plastic pipe pokes
out of fire-rated gypsum or masonry walls. The Hub-Seal
device is easy to install with quick inspections. It is
simply slipped over the hub portion of the fitting and
secured. The firestopping is completed at the same time the
rough-in piping is installed without any additional labor
cost. The drywall installers can then complete the drywall
with the firestops in place. The installation of a Hub-Seal
is simple, even if the poke-out is at an angle.
provide penetrations for all types of shower,
floor, hub and roof drains and other openings -
made with the sleeve coupling connection to the
drain top. It makes setting the drain much
easier. It comes complete with a mounting
flange for securing to the wood form and a
sleeve extension to match the elevation of the
finished floor. No more jury-rigging the
drains to secure them into the pour.
System “B” piping, firestopping is accomplished
simply by connecting the drains to the cast iron
or other metallic branch pipes. The bottom
connects to a P90 pipe nipple out of the sleeve
coupling to a transitional no-hub coupling to
the branch trap.
ProSet also provides area, planter and roof
drains. These, too, can be used in conjunction
when designing and installing an infrequently
used drain - without having to worry about the
installation, operation and cost of a trap
