Klein Tools offers a free service of recommending the proper grip for a particular application based on a sample of cable. All that is required is a minimum 6'-9' (2-3 meters) length of cable.
If there is ever a question about the safe condition of any grip, contact Customer Service at 847.821.5500 or 800.553.4676 or email HiSupport@kleintools.com.
commonly using the 1628-30, 1628-40 or 1628-50 series Chicago Grips – there is a risk of cable deformation under high tensions. To avoid this risk, Klein Tools recommends using two grips in tandem if the load is expected to exceed the lesser of 12,500 lbs. (5670 kg) or 40% of the ACSR conductor's tensile strength.

Best Practices for ACSS Conductors
1.
Larger than 0.953" outside diameter (approximately 600 MCM)
- Use the 1628-50 or 1628-40 series
Chicago Grips. The necessary grip size should be determined based on the cable outside diameter. For applications where the load is expected to exceed 10,000 lbs.
(4,536 kg),
use two of the appropriate grips in tandem to prevent cable deformation. See instructions for using two grips in tandem on page 17.
2.
Smaller than 0.953" outside diameter (approximately 600 MCM)
- Use two of the appropriate 1656 series
Chicago Grips in tandem. The necessary grip size should be determined based on the cable outside diameter. See instructions for using two grips in tandem on page 17.

RECOMMENDED CARE
Grip Cleaning, Lubricating and Inspecting
1
Step 1.Use the Klein Grip Cleaning
Wire Brush Set (Cat. No. 25450) or emery cloth to clean the surfaces of grip jaws (photo #1).
Step 2.
Spray de greaser on the grip jaws, all joints and moving parts (photo #2).
Step 3.Use the Klein Grip
Cleaning Wire Brush to remove dirt and debris from the grip jaws (photo #3).
Step 4.
Wipe grips dry with soft cloth.
Repeat all cleaning steps as necessary until grip is completely clean (photo #4).

2
Never repair any grip. Grips that are bent, misaligned or otherwise distorted should be discarded and replaced.
If there is ever a question about the safe condition of any grip, contact Klein Tools Customer Service directly at
847.821.5500 or 800.553.4676 or email HiSupport@kleintools.com.
Step 6.
Carefully inspect jaw condition, proper alignment of jaws and all parts, and possible distortion caused by exceeding safe-load specifications. Grips should operate smoothly. Spring-loaded grips should lock open with loop handle in “Down" position and should close automatically with loop handle “Up." The Klein Parallel Jaw Grip may be tested by opening and closing the jaws by hand, exercising proper caution. All parts and rivets should be checked for distortion (illustration #6).
Step 5.
Apply lubricant to all joints and moving parts. Do NOT lubricate gripping surfaces of jaws (photos left #5).

COMMON OVERHEAD APPLICATIONS
See Wire Pulling Grip Warnings on the inside cover.
www.kleintools.com
1. Set up the ratchet hoist and Chicago
Grip as shown here.
2.Ratchet the hoist until the cable is
lined up with the dead-end fixture.
3.
After the tension is approximately where
it will need to be after termination,
ratchet the hoist a couple more times
to accommodate for tension loss
after hoist removal. Consult cable
specifications to ensure the maximum
cable tension is not exceeded.
4. When finished, break the tension using the hoist handle, then use either the handle or drum knob to continue releasing the tension.
Sagging Using a Dynamometer
1.
Set up ratchet hoist, Chicago Grip
and dynamometer as shown here.
2. Ratchet the hoist until the
dynamometer displays the desired
tension. Consult conductorspecifications
or company procedures to determine
the appropriate tension.
3. When finished, break the tension
using the hoist handle, then use either
the handle or drum knob to continue
releasing the tension.
Splicing
1. Set up ratchet hoist and Chicago
Grips as shown here.
2.
Connect the KN1500PEX Web Strap
Ratchet Hoist to each grip, and
ratchet to the desired tension to
make the splice.
The cable can now be spliced
according to standard work
procedures and material guidelines.
3.
When finished with the splice, break
the tension using the hoist handle, then
use either the handle or drum knob to
continue releasing the tension.

COMMON OVERHEAD APPLICATIONS
COMMON OVERHEAD APPLICATIONS
Using Two ChicagoTM Grips in Tandem
For applications where the maximum load exceeds the safe load of an individual grip, or the cable is at risk of deformation, it is
recommended to use two Chicago Grips in tandem. Using two grips in tandem divides the weight load between both grips, allowing
for an effective work load increase of 1.5 times the safe load of each individual grip.
In some transmission applications—commonly using the 1628-30, 1628-40 or 1628-50 series Chicago Grips—there is a risk of cable
deformation under high tensions. To avoid this risk, Klein Tools recommends using two grips in tandem if:
For example, two Klein Tools 1628-40 Chicago Grips, each with a maximum safe load of 25,000 lbs. (11,340 kg) individually,
have a combined working safe load of 37,500 lbs. (17,009 kg).
• ACSR or AAC conductors – the load is expected to exceed the lesser of 12,500 lbs. (5,670 kg) or
40% of the conductor tensile strength.
• ACSS conductors—the load is expected to exceed the lesser of 10,000 lbs. (4,536 kg) or 40% of the
conductor tensile strength.
1.Place each grip on the same conductor, approximately five feet apart.
2.Connect a pulley block (leveling block) to the eye of each grip. This will maintain equal distribution of the weight
load between both grips.
3. Connect an anchored chain hoist of appropriate capacity to the block as shown in the image above.
4. Ratchet the chain hoist to the desired tension, as shown in the image below.
Materials Used:
Disclaimer: This is not intended to be a definitive instructional manual for completing the applications. Always consult company procedures
Klein Tools Chicago Grips, Klein Tools KN1500PEX web strap ratcheting hoist, Dillon Dynamometer, chain hoist, leveling block.
and material guidelines before attempting any application.
