Mark Placement and Install Cable.
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).
