Hoops (IHS) Cable
Installation Manual
Language: English
Thank you for selecting a DuctSox System. This manual will be helpful for the installation of a Hoops (IHS) Cable System.
Sections of fabric will be labeled, assembled, bagged, and boxed for shipping. More complicated systems will include a
CAD detail of the system identifying what is in each package. NOTE: The DuctSox cable attachment (Glider) is built for
1/8 in (3 mm) cable only.
Overview
Inventory
The rst step on any installation project is to read through this Manual thoroughly and review the components that need
to be installed. The best way to do this is to review the drawings of the project while reading the Manual, including the
CAD detail if applicable.
Shipping/Receiving
In some cases the DuctSox support system is delivered to the job site ahead of the DuctSox fabric sections. Depending
on the size of a project or order, a DuctSox system will be shipped by common courier in a single brown box or several
boxes. Larger orders will be shipped in crates by a common freight courier. Each DuctSox length should be packaged
into individual plastic bags and labeled according to size and number of pieces. Other markings or labeling may also be
incorporated for larger or more complicated systems. Be sure you have determined all boxes are accounted for.
Unpacking
Inspect shipment carefully and make sure all pieces are accounted for. Account for everything by emptying the box and
examining all contents. Note any missing or damaged pieces listed on the Bill of Lading.
Labeling
Each DuctSox section will be marked with the size and section number either inside the belt of the inlet or on a tag
inside the DuctSox near the zipper. The marking shall be the diameter, section length and total length. If custom labeling
has been used, locate an identication sheet that will be included with the delivery.
Equipment Required:
• Drill
• Level
• Tape measure
• Marker or pencil
• Wrenches for cable clamps and eye bolts (5/16 in and 9/16 in)
• Flat (standard) screwdriver
• Cable cutter

The following details are used for Galvanized Cable styles.
1. Eyebolts must be fastened to the structure of the building (including knee braces) by
others. They must be fastened in correct locations according to suspension style (Shown in
each suspension style’s section).
2. Hook Gripple®Turnbuckles to the installed eyebolts.
3. Insert cable into the plastic end of the Gripple®Turnbuckle and push/pull it through
the opening on the side of the Gripple®Turnbuckle.
Note: To release the cable hold in the plastic button and slide the turnbuckle.
To lock the button twist the plastic until tight.
4. Tighten the cable to 100 lb (445 Newtons) tension by pulling the cable tight and then
twisting the turnbuckles. Clip extra cable when nished, leaving about 3 in (76 mm) of
cable extending through the side the Gripple Turnbuckle.

The following details about Type 1 and Type 2 Kits are used for SS and Impregnated Cable styles.
Type 1 and Type 2 Kits
Type 1 and Type 2 kits are for straight runs of cable:
• Type 1: 50 ft (15250 mm) or less
• Type 2: 50 ft to 100 ft (15250 mm to 30500 mm)
• For systems over 100 ft (30500 mm), a combination of the kits should
be used.
These kits include one 6 in (153 mm) turnbuckle (two for Type 2), two
eyebolts, two cable thimbles, and four cable clamps.
Eye bolts must be fastened into the structure of the building by others
(this could include knee braces).
Cable is fastened directly to an eyebolt with a thimble and
two cable clamps. Take the cable end and thread two cable
clamps onto it. Now hook the thimble onto the eyebolt. Next,
thread the cable onto the thimble and through the eyebolts
(cable clamps are still on the cable). Now thread the cable
back into the cable clamps and tighten them.
Cable is then fastened directly to the turnbuckle with a thimble and two cable clamps. Slack in the cable is taken up by
the turnbuckle. If cable is still too loose after tightening the turnbuckle, loosen the cable, re-fasten cable to turnbuckle at a
tighter position, and re-tighten the turnbuckle. Do not over-tighten the turnbuckle, we recommend no more than 100 lbs (445
Newtons) of tensile force.
Intermediate Support Cable
Installed every 12.5 ft (3810 mm) or less to keep the DuctSox installed at a
consistent elevation (reduces sag of the cable).
Galvanized and SS
Impregnated

Step 3
Determine placement of cable (both cable path and elevation). The cable
must be mounted 1.5 in (38 mm) above the 12:00 location of the DuctSox.
Intermediate Cable supports are spaced no more than 30 ft (9150 mm).
T’s
There should be roughly 12 in (305 mm) from sidewall of DuctSox to the closest
edge of any knee-bracing. Structure too close to the main run may cause
premature failure due to abrasion from the structure.
NOTE: Offset distance of branch knee-brace from main trunk is approximately
half of the main trunk diameter plus 12 in (305 mm).
Elbows
Extended straps on heels of elbows are provided for support to cable suspension (Figure A). Vertical elbows are also
supported by extended straps (Figure B).

Step 4
Install DuctSox Fabric. DuctSox Inlet must be attached to the metal collar using screws (not
included) through plastic patches on the Inlet Belt. Be sure to locate the zipper start and seam
at the 12:00 orientation for proper alignment.
Twist and snap the Glider attachments of the DuctSox onto the cable (pliers may be helpful for
installation and removal of Gliders). Unzip ttings and slide them in place independently of the
straight sections. Cable Stops are installed at the Endcap Glider, at the Inlet Glider, and at each
Glider immediately adjacent to
all ttings. Leave them installed
loose until Step 5 is complete.
Close all zipper connections
before moving to Step 5.
The Cable Stop is used to keep sections of DuctSox from moving
lengthwise on the cable. They also are used to put a slight tension on
straight sections of DuctSox (straight sections may consist of more than
one zippered section of DuctSox). Nuts are tightened to lock the stop at
locations where Gliders are to be locked in place (see Step 5).
Step 5
Start Up AHU. Turn on the AHU and inate the DuctSox System. Check all Gliders and sections to ensure system is inating
properly. If required, move Gliders to eliminate puckering at binding locations. If lengths do not t properly, double check all
eld measurements and compare to drawings. If all measurements are correct, contact your DuctSox factory rep to discuss
options.
Once system is properly adjusted, inate the system, pull the last Glider in each straight section (including straight sections
between ttings), and secure tension using Track Stop Screws. Also, be sure to install a Track Stop Screw into the U-Track at
the Endcap Glider, at the Inlet Glider, and at each Glider immediately adjacent to all ttings.
The Track Stop Screw is used to keep sections of DuctSox from moving lengthwise in the U-track. They also are used to put a
slight tension on straight sections of DuctSox (straight sections may consist of more than one zippered section of DuctSox).
The screw is tightened into the bottom channel to lock the stop at locations where Gliders are to be locked in place.
If the system includes elbows or T’s, secure Gliders before and after these ttings. Failure to install DuctSox Systems correctly
may void warranty.

Step 6
Air Balancing. System must be balanced to design CFM and static pressure immediately after installation. Most DuctSox
Systems include a zipper at the inlet location for easy access to monitor ow.
If the fabric is uttering after balancing, please contact your factory rep immediately. Solutions to the uttering include
adjusting the Adjustable Flow Device (AFD), adding AFDs, or other solutions that would result in a less turbulent airow.
Laundering Instructions
Sedona-Xm, TufTex, Verona, DuraTex, Microbe-X, Rx, and Stat-X fabrics:
• Remove the DuctSox fabric from your system, being sure to unzip all sections. Take care in
recording where each section was installed.
• Remove the hoops from the DuctSox system by simply twisting the attachment sideways. Note:
the hoop attachment only slides one way.
• Turn soiled side out and soak in cold water for 30 minutes.
• Wash cold, gentle cycle.
• Rinse thoroughly (repeat cycle if water/DuctSox still soiled).
• Drip dry or no-heat tumble dry.
