OVERVIEW
SPECS

Dua-Pull grips from KELLEMS are the highest strength pull grips manufactured for overhead transmission line stringing applications. They have a dual function of working with both bare and insulated conductors and synthetic rope which is not provided by any other grips.

Key to the exceptional strength and gripping ability of the Dua-Pull grips is its two under-two over mesh design. This puts more steel mesh in contact with the surface of the conductor or rope, thereby increasing gripping ability even on slick, stretchy synthetic ropes. Dua-Pull strengths and gripping have been increased over conventional high-strength pull grips by as much as 200 percent. Dua-Pull grips are as strong or stronger than most of the high-strength conductors and ropes made.

Only six sizes are needed when selecting a grip. Dua-Pull fits conductor diameter ranges from .19 in. to 1.90 in. and rope diameter ranges from .25 in. to 2.10 in. with approximate breaking strength ranges from 6,500 lbs. to 66,500 lbs. This range covers most utility and high line stringing operations. Larger sizes will be manufactured to meet specific requirements.

In answer to the need for a simplified way to select the correct grip to fit rope or conductor, Kellems has color-coded each of the Dua-Pull grips. Color has been applied to a sleeve above the grip collar representing the rope or conductor diameter range with which the grip is to be used. There can be no mistake in selecting the correct grip for the job. With the help of the hand Dua-Pull selector chart, job site grip selection is accurate, easy and fast.

SHERMAN + REILLY SWIVELS AND THE PULLING LINE CONNECTORS ARE AVAILABLE FOR MATCHING DUA-PULL GRIPS FOR LINE STRINGING APPLICATIONS. THE SWIVEL PROVIDES COMPLETELY INDEPENDENT ROTATION BETWEEN THE CONDUCTOR AND THE PULLING LINE. THE CONNECTOR IS DESIGNED FOR APPLICATIONS WHERE SWIVELING ACTION IS NOT DESIRED. DUA-PULL GRIPS WILL ALSO ACCOMMODATE THE SELF-DAMPENING CONDUCTORS (SDC), BUT SPECIAL INSTALLATION IS REQUIRED. CONSULT THE CONDUCTOR MANUFACTURERS FOR INFORMATION.
