The Jumper Hook is designed especially to easily prevent cross phasing without the use of time consuming tapes, bungee cord or ropes. The jumper hook can be hand installed and also has a side hole to permit remote installation with a shotgun stick.

Macron Safety



Hotline work practices do not permit energized lines from crossing another phase. When working with jumper leads this is a difficult task, jumper leads usually sag during use and tend to cross lower phases creating a potentially dangerous situation.

Position a number of Jumper Hooks over conventional class 2 or class 3 line hose. Simply place the jumper lead in the lower portion of the Jumper Hook to keep parallel to the main line and prevent sagging. The Jumper Hook is manufactured from a tough weather resistant polymer. The jumper hook exhibits over 50 kV flash-over resistance and resistance to tracking.

  • Product dimensions: 11"length x 4.5" width x 1/2" thickness

Determine the Correct Protection Level, To evaluate Fire Retardant clothing materials in order to measure the heat transferred through the fabric, two values are calculated: Arc Thermal Performance Value (ATPV)...the minimum energy causing the predicted onset of second-degree burns and Heat Attenuation Factor (HAF)...the percentage of total energy of the arc that the fabric prevents from passing through, OSHA requires that each employer must assess the potential hazards in the work environment and determine the appropriate clothing materials using ASTM PS57-97. Always do a hazard assessment. You will need to know electrical system voltage, fault current available, number of phases, Arc time duration, estimated Arc gap, minimum distance from the Arc, and Arc configuration.
