Two-Pole Strain Carriers

Heavy Duty (15,000 lb.)

Tested per OSHA & ASTM F711
Two-pole Strain Carriers relieve strain from an insulator string to permit removal from energized lines. Normally used on a single string of insulators, these carriers sometimes are used for multiple strings where conductor-end hardware permits attachment.

Available here as complete assemblies, separate components also may be ordered. For adjustable strain poles, see page 2253; for yokes, sockets and trunnions, see page 2255.

Yokes are fabricated from high-strength aluminum plate and include a steel chain assembly for anchoring the back plate to the structure. Conductor-end yoke includes a hook and a machined socket (C4011894).

Maximum load rating for each of the strain-carrier assemblies listed below is 15,000 lb. per insulator string.

Common features for all units listed:

  • Two 2"-diameter Epoxiglas poles
  • Yokes are 26" wide on pole centers
  • 2-ft. adjustment in 6" increments on five stainless-steel pins per pole
  • 12"-long Strain Jacks

Standard Duty (6,500 lb.)


Tested per OSHA & ASTM F711
This tool assembly has the same basic use as the two-pole strain carrier: Relieving strain while removing a single string of insulators. The distribution strain carrier has a compression deadend yoke at the hot end which is equipped with a various shoe sizes to grip the conductor ahead of insulatorconductor hardware with a compression lever-type action, gripping tighter as the load increases. The various shoes furnished with the kit fit conductors from 0.292" through 0.806" (No. 2 through 397.5 ACSR).

Maximum load rating for each distribution strain-carrier assembly listed below is 6,500 lb. per insulator string.

Common features for all units listed:

  • Two 1 1/4"-diameter Epoxiglas poles
  • Yokes are 21" wide on pole centers
  • 2-ft. adjustment in 6" increments on five stainless-steel pins per pole
  • 12"-long Strain Jacks
Catalog Number Nominal Pole Length Distance Between Yokes Weight, each assembly
Minimum Maximum
C4010411 6 ft. 47-1/2" 81" 82 lb. / 36.9 kg.
C4010410 8 ft. 71-1/2" 105" 92 lb. / 41.4 kg.
