MIL-T-43435 Sizes 1, 2, 3, 4, 5 Binding cord

This U.S. military standard defines a tape used for cable bundling.
Bundling is a technique used to group electrical wires into a bundle using bundling twine.
Although bundling can be done using Rilsan or Colson-type cable ties, string bundling saves space, binds cables without risking damage, and ensures a secure hold even under vibration or high temperatures.
