• The STRA rail (1) is mounted at a height (4) between 12 and
14 ft (3,7 and 4,3 m) over the oor on the side in which the
tailpipe (2) is located.
The rst rail hanger leg should be approximately 4 to 5 ft
(1.2 to 1.5 m) from the end of the STRA rail.
• The rail should be mounted 18 to 24 in. (460 to 610 mm)
from the body of the vehicle (5), and positioned on the
tailpipe side of the vehicle. Preferably the rail is on or within
the boundaries of the exit door. Measure the garage door and
truck width in order to determine the rail mounting position.
• The rail should be mounted immediately under a sectional
door with a clear height from the track to the door of 4 to 6
in. (100 to 150 mm).

• The recommended distance from the end of the rail to the
door(s) (6) can be found in the installation table on page 6.
WARNING!
Product may contain sharp edges. Use care when
servicing the unit, failure to do so could result in
minor personal injury.
ATTENTION
Based on the door height and distance from end of
the rail, a cantilever under the door may be required,
so that the vertical hanger leg does not obstruct the
door track. Typically, the cantilever is required once in
a back-in-system and twice on a
drive-through-system.
4.4 Splicing two rails
To splice two rails, position the rail sections on saw horses.
• Insert and center a splice plate 4 in. (100 mm) (2) inside the
rail, clamp in place with a C-Grip and drill 2 Ø 0.42 in. (10,5
mm) holes that are 2.6 in. (65 mm) apart on the top and on
both sides.
The splice is mounted together with 12 pcs of M10 x 25 mm
(0.42 in.) bolts.*
• Use the upper v-groove to drill the holes in the rail and insert
the bolts but leave them loose (3).
• Silicone the joint and slide the other rail section onto the
splice. Line up straight in both directions and clamp.
• Drill the same holes on the mating rail.
• Tighten the bolts in sequence - rst tighten the top bolts, and
then the remaining bolts on the sides.
*Fastening material is included in the splice package.
ATTENTION
Make sure the spliced rails are straight and the rail
channels are lined up. This will ensure that the rubber
seal can be inserted properly.
4.5 Assemble the legs and the rail
• Support legs can be attached to the following:
- Steel beems - use unistrut bar clamps (1). To attach to the
top or bottom of a bar joist, use a thru bolt in the slot of the
bar joist.
- Drywall ceiling with wood framing - locate center of trusses,
cut strut to span 3 trusses, drill 1/4 in. pilot holes and
mount strut using 3/8 in. X 3 1/2 in. grade 5 lag bolts.
- Poured or Pre-Cast Concrete - use a stud or wedge type
concrete anchor usually a 3/8 in. X 3 in.
• Mount the support leg to the roof or to beams. The rst leg
should be 4 to 5 ft (1.2 to 1.5 m) from the end of the rail.
Leg assemblies will need to be placed every 10 to 12 ft. (3 to
3,6 m) and braced side to side using the appropriate length
(20, 30 or 72 in.) side brace kit.
Note: Longer braces can be made out of ¾ in. EMT conduit
and attached to the leg using the Plymovent leg/brace
mounting kit. You should have at least one long brace
running front to back.
• Fasten the top suspension upper bracket to the support leg.
Predrill 0.2 in (5 mm) and then 0.42 in. (10,5 mm) (3 and 4)
that align with the holes in the bracket. Position the bracket
on the leg so it is centered, then drill the third hole in the leg
(2). Add bolts and nuts but do not tighten, as you will need
to cut the support leg.
• Mount the the support leg to the roof or to the beams. To
calculate the leg length, determine the mounting height of
the rail, then subtract that dimension from the bottom of the
strut. Cut the support leg to this length.
• Side suspension: plummet the position of the supports and
attach the side suspensions to the rail. Center a triangular
foot and drill 2- 13/32 in. holes to attach the foot. Mount top
suspension lower bracket to the support leg without
tightening the bolts. Mount the support leg to the roof or to
beams. Attach the leg assembly to the strut on ceiling using
3/8 in. strut hardware. Attach the side brace kit (5).
• For multiple legs, turn the side braces perpendicular to the
rail and install one long front to back brace. Repeat for each
leg assembly.

4.6 Inserting the rubber seal
1. STRA prole
2. Rubber seal
3. Tool no. 0000102158
• Turn the rail prole with the opening upwards. The rubber lip
seal can be easily installed with the Plymovent STRA Lip Tool
before hanging the rail from the support legs; or you can
install the lip after the rail is hung from the support legs.
• The rubber lip seals are directional and must be installed with
the inside bend towards the center of the rail (angled inward
and facing each other). With the rail still on saw horses, install
the rubber lip with the bend facing inward. To make this easier,
spray the lip and aluminum channel with a soapy solution.
• Start installing the rst 6 in. (150 mm) of rubber lip by hand
using a screwdriver and then position the lip tool on the rail to
roll the rest of the lip into the bend. Cut the ends at a 90
degree ush with the end of the rail. Repeat for the other side.
4.7 Connect to duct and lift the rail
• On the top of the rail, lay out 3/8 in. holes for the leg
mounting feet locations, to match the distances between the
leg assemblies previously hung from the ceiling. The
maximum end of rail to the rst hanger leg should be 4 to 5
ft (1,2 to 1,4 m). A cantilever under the garage door may be
required.
• Pre drill these holes. Raise the pre-assembled rail using
multiple scissor lifts or lifting mechanisms such as a chain
fall. Position rail under leg assemblies and attach with
hardware.
• Plymovent recommends lifting a continuous length of rail up
to 100 ft (30 m) maximum, in which the maximum distance
between the lifting points is 33 ft (10 m).
Top suspension:
• Lift the rail according to the instruction and x the bolts on
the RRTS lower bracket (1).
• When the rail is in the right position x the suspensions with
the bolts.
• Fasten the suspensions with the security bolt.
Side suspension:
• The leg is connected to the vertical support legs with
couplings.
• Adjust the rail both vertically and horizontally until it is level.
• Tighten the couplings thoroughly and screw a safety bolt,
which is required (2).

• To connect the rail to the fan and the duct system by the
connection socket (3), cut a 19.6 in (500 mm) x 2.3 in. (60
mm) hole in the side of the rail prole. Apply silicone
sealeant to the bottom ange of the duct connector and
attach with the provided self-drilling screws. Repeat this step
if you are using multiple duct connections on longer rails.
4.8 Assemble and hang the hose/grabber
1. Upper hose
2. Saddle
3. Balancer
4. Safety Cable
5. Locking Cable
6. Mid Hose
7. Safety Disconnect Handle
Follow these steps to assemble and align the exhaust hose
assembly:
• Mount the upper hose (1) to the trolley using a hose clamp.
• Attach the upper hose to the short side (from the tab) of the
metal saddle (2). You may need to twist the hose to to have
the u-bend or loop positioned away from the vehicle in the 3
o’clock position if looking down at the crab trolley, with the
balancer at the 12 o’clock position.
•
• Install the balancer (3) using the caribiner hook and safety
cable (4), and attach the Balancer Locking Cable (BLC) to the
carabiner which is attached to the trolley (5). Assemble the
BLC using the length listed in the Installation Table on page
10. Ideally, 6 in. (15 cm) of the Balancer cable should be
exposed when the Grabber nozzle is connected to the
vehicle.
• Install the BLC so that it is on the back side of the balancer
and away from the adjustment locking clip. This will keep the
BLC from coming into contact and potentially breaking the
locking clip. The balancer snap hook should be oriented with
the catch or door of the hook on the same side of the
balancer as the locking clip. This will ensure that the BLC
does not open the snap hook, allowing the BLC to come
loose. The BLC attachment to the metal saddle snap hook
should be opposite of the catch or door so that it does not
open it.

• Attach the mid hose (6) to the long side of the metal saddle
with the supplied hose clamp. The ST mid hose is directional,
so install with directional arrow pointing up or with the
airow.
• With the balancer holding the hose all the way up cut the mid
hose at approx 4 ft (1,2 m) from the oor and attach to the
Safety Disconnect Handle with the supplied hose clamp (7).
• Make sure the height of the Grabber nozzle is between 14 in.
and 18 in. (35,5 to 45,7 cm) from the nished oor.
• Slide the completed trolley in the rail with the
balancer facing the driving direction / exit door.
4.9 Installing the end caps
• With a 8.5 mm drill make a hole at 0.9 in. (22 mm) from end
of rail (1).
• Mount end socket with hydraulic shock absorber at the exit
side and mount the end cap with cover or end cap with duct
connection with 4 pcs of M8x20 bolts and nuts that are
provided. Do not use self-drilling tech screws (2).
• Repeat for the back end cap, but do not install until the rail is
hung, so you can install the crab/trolley.
• After installation, ne tune the BLC if the disconnection point is
not close enough to the door.

4.12 Modify the tailpipe
In case you want to install a 5 in. (125 mm) conical tailpipe
adapter and the vehicle uses a 4 in. (100 mm) tailpipe, you will
have to install a tailpipe reducer. The tailpipe reducer is a part
that adapts the 4 in. (100 mm) tailpipe into a 5 in. (125 mm)
tailpipe so the conical tailpipe adapter can be installed. The
tailpipe reducer is positioned over the existing tailpipe and xed
using a 4 in. (100 mm) tailpipe clamp. Product number: Refer
to your FIRE Price list for specic product numbers.
4.13 Check the balancer tension
The balancer is delivered from the factory with pre-tension
already set. After every component of the system is installed,
you may need to adjust the balancer pre-tension to its nal
setting, to ensure that the balancer is functioning properly.
Increase or decrease the spring tension until the rubber stop
loosely hits the balancer housing and cable is retracted.
It is possible the balancer tension needs to be ne-tuned after
the total system is installed and a test run is done.
ATTENTION
The balancer is delivered under tension. Be careful
when unwinding this balancer.
4.14 Safety Disconnect Handle
Function:
The safety coupling disconnect opens in case of missue of the
systemor failure of the disconnection and can always be re-used.
Adjustment:
The Safety Disconnect Coupling is delivered completely
assembled with a preset tension. The standard setting on
delivery gives you a release force of 100 lbf (nominal) (450N)
and a reconnection force of 35 lbf (150N).
Release force:
You can adjust the safety coupling disconnect by using dierent
springs available from Plymovent. These are not included, so
please contact your Plymovent authorized distributor.
ATTENTION
After the Safety Disconnect has released please check
if all spring blocks in the product are free of damage
and functioning correctly. Any damaged parts should
be replaced and the correct functioning should be
veried. If the Safety Disconnect is not functioning
correctly, it can potentially cause damage to person or
property.

Magnetic Grabber tailpipe bends as well as direct onto the
Magnetic Grabber tailpipe connector. The tailpipe reducer pack
allows a wide range of exhaust pipes to connect to the
Plymovent system.
Tailpipe support bracket
The tailpipe support bracket can be used for various dimension
exhaust tailpipes and ensures a secure connection between the
tailpipe and body / chassis. In some cases, you may need to
divert the exhaust ow from the tailpipe to the side of the
vehicle. The Magnetic Grabber®connector can then be installed
to this modication.
When a tailpipe modication is needed, Plymovent recommends
you consult the manufacturer of the vehicle, to ensure a correct
and sturdy installation of the Magnetic Grabber®connector.
5 USE
The STRA is an automatic, magnetic or pneumatic exhaust gas
extraction system designed for the exhaust extraction of re and
rescue vehicles with low level, undercarriage exhaust pipes. The
system is used to remove harmful vehicle exhaust emissions
from the facility by capturing and removing the exhaust at the
emission source, the exhaust pipe.
As a vehicle moves within the facility, the nozzle must be
connected to the vehicle. The connection of the nozzle to the
tailpipe will activate the fan. The extraction hose connected to
the nozzle moves along with the vehicle.
Exhaust gases pass from the nozzle through the extraction hose
and into the ducting and extraction fan before escaping to the
atmosphere.
As the vehicle exits the facility, the trolley moves along to the
end of the rail. The balancer locking cable prevents the balancer
from unwinding and pulls the nozzle from the tailpipe, allowing it
to disconnect. The disconnection of the nozzle automatically
stops the fan.
5.1 Operating the Magnetic Grabber®
5.1.1 Connecting the Magnetic Grabber
Please ensure that, on the side of the vehicle where the system
is installed, no persons are present in an area of 3 ft (1 m)
under and / or around the STRA system and /or between the
vehicle and the entry / exit door when the vehicle exits the
building. This way possible injuries can be avoided by a possible
backwards motion of the Grabber in the direction of the station
and park position.
When a vehicle returns to its bay the Magnetic Grabber nozzle
can easily be attached to the conical tailpipe adapter.

160420/0 STRA MG manual EN - 12
The Magnetic Grabber nozzle must be placed straight onto the
conical tailpipe adapter, but to connect it is easiest to rst attach
the top of the Magnetic Grabber and then press down on the
safety disconnect in order to attach the lower part of the
Magnetic Grabber.
The conical design of the connection surface ensures safe and
easy positioning.
