Warnings:
- TREE-GRIP Dead-ends should only be applied to the specified strand sizes.
- Follow normal installation procedures when installing cabling between two boughs or branches using TREE-GRIP Dead-ends.
Product Usage Instructions
- Match the correct (EHS) or Common Grade strand size needed for the job with the corresponding TREE-GRIP Dead-end. Ensure that the strand is left hand lay. Tape the area of the strand to be cut to prevent individual wires from separating after cutting.
- Insert the correct thimble size into the TREE-GRIP Dead-end’s cabled-loop. Cross the longer leg with the already completed shorter leg at the cross-over mark to secure the thimble in place.
- Wrap the short leg of the TREE-GRIP Dead-end around the EHS strand within two wraps (pitch lengths) of completion. Pull the legs away from the strand during the wrapping procedure to facilitate ease of application.
- Continue wrapping the long leg around the strand within two pitch lengths of completion. To ease application of the last two pitch lengths, split each leg into two subsets and wrap each subset individually to completion.
- Ensure all leg ends are properly snapped onto the strand to prevent unwinding.
- Handle and install TREE-GRIP Dead-ends carefully to prevent distortion or damage. Follow the provided illustrations for correct assembly.
Installation Guidelines:
- TREE-GRIP Dead-ends may be removed and reapplied up to three times if necessary for adjusting cabling installation on new construction.
- TREE-GRIP Dead-ends should not be reused after original installation.
- TREE-GRIP Dead-ends should not be used as tools (e.g. come-alongs, pulling-in grips) and should only be applied to the designated thimble size.
- Do not apply TREE-GRIP Dead-ends over drive hooks, eye bolts, eye nuts, etc. without a thimble.

WARNINGS
- • For TREE-GRIP Dead-ends to function as designed, their length must not be reduced or altered.
• Extra precautions should be taken when it is anticipated that larger trees or heavy limbs will be subject to dynamic activity due to higher than normal wind loadings. Contact your local PLP representative for recommendations.
GENERAL
TREE-GRIP Dead-ends (Cat #’s TG-1250, TG-1251, TG-1252 and TG-1253) should be
applied to extra high strength (EHS) or Common Grade left hand lay (LHL)
galvanized steel strand sizes 3/16, 1/4, 5/16 and 3/8 inch respectively.
When installing “cabling” between two boughs or branches using TREE-GRIP Dead-
ends, follow normal installation procedures.
Step #1
Match the correct (EHS) or Common Grade strand size needed for the job with the corresponding TREE-GRIP Dead-end making sure the strand is left hand lay. Then tape the area of the strand to be cut. This will prevent the individual wires from separating after the cable cutter cuts the strand.
NOTE: The PREFORMED Safety Guy Wire Dispenser, Catalog No. SGD-0700, is a perfect accessory when carrying and working with extra high strength strand.
Step #2
Lay the taped end of the cable in the TREE-GRIP® Dead-end’s short leg,
slightly above the cross-over mark.
Step #3
Once the cable has been positioned correctly, continue to wrap the short leg
of the TREE-GRIP Dead-end around the EHS strand within two wraps (pitch
lengths) of completion.
During the wrapping procedure, be sure to pull the legs away from the strand.
This will facilitate the ease of application.
Step #4
Insert the correct thimble size in the TREE-GRIP Dead-end’s cabled-loop and
cross the longer leg with the already completed shorter leg at the cross-over
mark. The thimble is now secured and cannot fall out.
Step #5
Continue wrapping the long leg around the strand within two pitch lengths of completion.
NOTE: To facilitate the ease of application of the last two pitch lengths
of the legs of the TREE-GRIP Dead-end, split each leg into two groups
(subsets) and wrap each subset individually to completion.
PLP TIP: Be sure all leg ends are snapped properly on the strand. If not applied correctly, the rods may unwind from the strand.
Step #6
Completed Application – If less tension is desired after the initial
installation
(within 90 days), follow this procedure: Unwrap both legs of the TREE-GRIP
Dead-end within 2 pitch lengths of the cross-over mark and allow the strand to
slowly slide through the legs until the desired tension is achieved. Then
simply wrap both legs back on strand to completion.
Installation Guidelines
- TREE-GRIP Dead-ends are precision devices. To ensure correct assembly, they should be handled carefully. To prevent distortion or damage, they should be installed as illustrated.
- TREE-GRIP Dead-ends should be stored in cartons under cover – preferably shelf storage – until used.
- TREE-GRIP Dead-ends may be removed and reapplied three times. If necessary, on new construction, for the purpose of adjusting cabling installation.
- TREE-GRIP Dead-ends should not be reused after original installation.
- TREE-GRIP Dead-ends should be used only on the size strand for which they are designed (see table on Page 1).
- TREE-GRIP Dead-ends should not be used as tools; that is, come-alongs, pulling-in grips, etc.
- TREE-GRIP Dead-ends should be applied only to the thimble size designated, see table on Page 1. (They are not to be applied over drive hooks, eye bolts, eye nuts, etc. without a thimble).
- TREE-GRIP Dead-ends should be used on hardware that is held in a fixed position; the fitting should not be allowed to rotate or spin.
- TREE-GRIP Dead-ends should be used with compatible strand and fittings.
- Lay direction of both the TREE-GRIP Dead-ends and the strand should be left hand lay.
- TREE-GRIP Dead-ends should not be used as false dead-ends.
- If in doubt about fittings or application, contact your local PLP representative for an engineering recommendation.
