DCD Metric Expanding Pullers – 00620 Series

These products are designed to grip polyethylene ducting using expanding jaws to grip the
inside wall of the duct. This causes the pulling load to be spread around the circumference
of the duct and allows a maximum load to be applied without damage to the ducting.

Care should be taken at all times not to exceed the yield value of the ducting since this may
cause permanent deformation to the duct as well as loss to the integrity of the polyethylene.
On thin wall ducting, it is recommended that an outer duct sleeve be used to prevent the duct
stretching during installation. A firmer and more stable grip will also be obtained when this is
done. Use of a duct plugger will help to prevent mud and slurry from entering past the puller
into the ducting. Duct wall thickness is normally designated by an SDR value. The lower the
SDR value, the heavier the wall thickness. These products can be used on SDR 11 through
SDR 17 ducting.

When ordering 10” and 12” Duct Pullers, the inside diameter of the duct must be known in order to
select the correct duct puller part number. Jaw sets are easily interchangeable in the 10” and 12”
size pullers. Alternate jaw sets for different SDR values can be purchased separately.
