Guy Deadends for High Tension Terminations

Hubbell Adjust-A-Grip® guy deadends offer the ease of installation and the performance that is critical for high tension terminations, associated with transmission towers and antenna structures.

Guy deadends are the connection between guy wire and anchor in a down guy application and must be sufficiently strong to exceed the rated breaking strength of the strand. A one-half inch diameter guy strand rated for 26,900 pounds is considered the threshold from distribution to transmission guying that would require a high-tension guy.

Hubbell Adjust-A-Grip® guy deadends offer the ease of installation and the performance that is critical for high tension terminations associated with transmission towers and antenna structures.

Adjust-A-Grip deadends can be applied on guy strand as small as ½” dia. or as large as 1-1/2” dia. and are rated up to 142,900 lbs. Adjust-A-Grip deadends are offered for galvanized steel strand that meet the requirements of ASTM A-475 or aluminum coated strand per ASTM A-474 or B-416. 

 

Reliability and Performance of the Adjust-A-Grip Guy Deadends

  • Design – The dual gripping design that consist of a socket/wedge and helical formed wire grip, ensures that Hubbell Adjust-A-Grip deadends consistently exceed 100% of the rated breaking strength of the intended strand.
  • Functionality – Adjust-A-Grip deadends are offered in two designs; one with a non-adjustable U-bolt and one that offers 18” of adjustability that facilitates installation or re-tensioning at a later date.
  • Service Record – The reliability of the Adjust-A-Grip design has been successfully proven in the field for the past 50 years 

 

Ease of Installation for Remote Job Sites

  • No Special Tools – Basic hand tools, normally just a crescent wrench, are all that is required to install the Adjust-A-Grip. This is in contrast to a crimp type deadend which requires heavy crimping equipment that must be transported to the often remote job site.
  • Self-Contained Kit - With Adjust-A-Grip deadends, all components can be shipped to the job site in a single package. There’s no purchasing of additional components, such as with an individual deadend and turnbuckle design.
  • Compact Design – The Adjust-A-Grip deadend is a compact design that allows the anchor end to be completely installed from the ground, without the need for a step assistance. 
  • Correlation to Guy Tension – With Adjust-A-Grip deadends, guy tension can be closely approximated by measuring the torque on the U-bolt load nuts. For accurate results, the U-bolt thread and nut must be lubricated with commercially available anti-seize compound. Torque to tension correlation charts are shown in the Adjust-A-Grip catalog.
