Cable Installation Using Pulling Equipment
The low co efficient of friction of pre lubricated PVC will allow pulls in excess of
4000' for Multi-Gard unless abrupt changes are in the route. Pull speeds of 100
200 ft. per minute are acceptable.
Cable pulling operations:
1. Multi-Gard innerducts are pre lubricated. Additional Polywater lubricant
may be used for longer pulls.
2. Align the pull blocks or sheaves so the pull line passes directly and freely
from the innerduct entrance. Cable should be fed from the top of the reel.
3. Choose swivel with load rating at or below maximum pull limit. Attach
swivel between pull line and cable pulling eye or basket grlp.
4. Maintain constant pulling tension to avoid stop/start. A monitoring device
should be used to avoid over tensioning the cable. Most outside plant
cables are rated for 600 Ibs. Check with cable manufacturer for specific
pulling tension.
5. Leave slack in each handhole where racking will be needed.
Innerduct Racking Using Pulling Equipment
The racking operation should be done after the cable has been pulled through
the Multi-Gard.
1. Place PVC corrugated split innerduct over slack cable.
2. Secure cable in innerduct against handhole/manhole wall out of way.
Cable Installation Using Jetting Equipment
Multi-Gard with the new Air Gard™ gasket and pre lubed PVC innerduct is ideal
for jetting cable.
Jetting cable operations:
1. Set up jetting equipment for easy accessibility to PE innerduct secured to
Multi-Gard.
2. Blow foam carriers through innerduct until clean and dry.
3. Multi-Gard is now ready for jetting according to high speed air blowing
system manufacturer's instructions.
4. Leave slack in each handhole where racking will be needed.
