The Polywater Front End Pack is a plastic, lubricant-filled bag. It lubricates ahead of the cable during the pull. It eliminates the need for hand application in many pulls. Proper Front End Pack use lubricates far down the conduit where normal lubrication is inadequate.
Front End Pack Bags -- A Cable Pulling Lubrication System That Supplements or Eliminates Hand Application of Lube During Wire Installations.
Two different sizes are available. Both contain Polywater J High Performance Cable Lubricant.
A one-quart pack (cat# J-99/J-27, or WJ-99/WJ-27 for winter-grade) for use in 2" and 3" conduits. The one-quart pack is 1¾" in diameter by 24" long.
A half-gallon pack (cat# J-110/J-55, or WJ-110/WJ-55 for winter-grade) for use in 3½" and larger conduits. The half-gallon pack is 3" in diameter by 14" long.
QUANTITIES
When only Front End Packs are used for a pull, the number of packs recommended for a pull is:
Number of packs required = 0.003 x T x L x D
Where:
T = 1 for J-110/J-55 packs (half-gallon size)
or
2 for J-99/J-27 packs (one-quart size)
L = Length of pull in feet
D = Nominal I.D. of conduit in inches
The quantity appropriate for a difficult pull may be up to +50% above this average, depending on conduit fill, conduit type and condition, number of bends, and pulling environment.
