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.Note: Safe Working Load is based on the duct yield strength to protect from creep failure.
