OvalSox™Cable
Installation Manual
Language: English
Thank you for selecting a DuctSox System. This manual will be helpful for the installation of a OvalSox™ 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 guide 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 guide, 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

THOROUGHLY BEFORE BEGINNING.
Step 2
Prepare metal inlet collar for fabric connection.
• Conrm inlet air supply location.
• Conrm inlet air supply size.
• DuctSox inlets are manufactured 1/2 in (12 mm) larger than specied
to t over metal inlet collar.
• Metal collar length should be 6 in–10 in (150 cm to 250 cm) for
secure fabric attachment.
• Edge Guard (provided) should be installed on the edge of the metal
collar to reduce fabric wear from the metal edge.

DuctSox®Installation Manual OvalSox™Cable
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.
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).

Step 3 – Installation
Determine placement of cable (both cable path and elevation). The cable must be located X inches apart and 1 in (25 mm)
above the 12:00 location of the DuctSox (match this up to the chart and the drawing). Intermediate cable supports are spaced
no more than 12.5 ft (3810 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.

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. The screw fasteners are particularly
important when your inlet is oval or rectangular, but they should always be used. 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.
Connect hanger rods to the
OvalSox. See illustration below. Connection of hanger rods to the OvalSox may be done prior to locking Glider attachments
onto the cable, if desired.
First slide the rod into the rope loops. Then attach the rod clips to the rod and the webbing.
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.
• Turn soiled side out, 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.
