ABSTRACT:
A pulling grip for drawing a cable through a conduit is disclosed. The pulling grip includes a braided gripping sleeve that has an opening at one end which provides access to a central space surrounded by the sleeve. An eye for attachment to a pull tape is positioned at the opposite end of the gripping sleeve. The cable is received within the gripping sleeve, which is biased to engage and grip the cable along its length. Due to the trellis effect, the gripping sleeve grips the cable with greater force when under tension. One end of an elongated protective shroud is attached to the opposite end of the gripping sleeve. The other end of the shroud is free to move lengthwise along the sleeve toward and away from the attached end. The shroud prevents the gripping sleeve from contacting the conduit and its contents and thereby prevents the pulling grip from damaging these items during the pull.
