Power Bands are a high strength shock cord assembly.
Power Bands have Stainless Steel, Galvanised Steel, Nylon or Aluminium thimble(s) and are bonded with 2 servings of whipping to ensure strength under heavy loads. We can also supply with soft eye terminations, double-whipped or crimped and covered. Power Bands are largely used in the Defence industry but are also used in leisure/adventure applications. We can make to customer specifications or drawings, or design suitable Power Bands in consultation with customers.
Heavy duty (BS3F70), light duty (BS3F71) Superstretch or commercial shock cords are used in these assemblies, depending on the application.
