Abstract
Abstract A pulling eye assembly is adapted for attachment to the end of a communication cable whereby linear pull can be applied to the cable end to draw the cable into place in the air on poles or underground through conduit. The outer portion or sleeve of the assembly may also be used for pressurizing air or gas filled cables to exclude moisture.
