KELLEMS PULLING GRIPS
• for Overhead Pulling
• made of high-strength galvanized-steel strand
Features & Applications
• Designed for overhead pulling
• Made of high-strength galvanized-steel strand
WARNING:
When selecting slings, the following must be
considered:
1. Do not run grips or swivels over bullwheels while under
tension
2. Two Punch-Lok® bands should be firmly attached,
approximately 1” and 2” from the grip’s tail. Banding is
required to ensure maximum reliability and guard against
accidental release
3.
DUA-Pull type grips only:
Double-braided rope, as in 2-in-1 type, must be back-spliced for approximately 2/3 of the
mesh length for best gripping results. Grip size must be selected by diameter of back splice.
DUA-Pull
®
Type Grips
Features
• Highest-strength pulling grips manufactured for
overhead transmission line stringing
• Work with both bare and insulated conductors, plus
synthetic rope
• Two-over/two-under weave design delivers exceptional
strength and gripping ability
• This is made possible by putting more steel mesh in
contact with cable or rope surfaces
Applications
• Primarily used in overhead transmission line
construction
• Designed for loads and safety considerations that
require an extra high-strength grip
• Will mate with swivels and link-type connectors
• Also used for attaching pulling lines to conductors,
conductors to running boards, and “double socking” for
conductor-to-conductor connections
• DUA pull line accommodates ACSR, ACAR, plus, all
aluminum and copper conductors
• Grips also accommodate ground wires, messenger
strands, plus wire and synthetic ropes

Never use wire mesh grips up to listed approximate break-
ing strength. Always use an appropriate safety factor when
selecting grips for the working load in your application.
Kellems minimum recommended factor of safety for pulling
grips is five (5). Additionally, banding the tail end of the grip
is recommended for maximum grip performance.

Features
• Designed for pulling ACSR, aluminum or copper bare
conductor, ground wires, messenger strands, wire rope
and insulated cables
• Made of high-strength, galvanized-steel strand
• Feature a mesh construction of single, double and triple
weave for firm holding power
• Endless-weave Grip end lies flat on the cable and will
not snag
• Flexible Eye: Flexible, wire-rope eye will mate with a
swivel and pass through blocks and sheaves without
binding
Applications
• Ideal for overhead transmission and distribution line
stringing for moderate loading
• An economical tool for attaching conductors to pull
lines and “double socking” for conductor-to-conductor
connections
