The REELEX Box
All REELEX packages require a payout tube. The purpose of the payout tube is to ensure that each twist in the coil is resolved inside the package prior to existing the coil so as to result in smooth, twist-free payout. Payout tubes also serve to prevent the coil from rotating inside the package. If a payout tube is not used, some loops of the coil would exit the package resulting in twists and possible tangles.
Payout Tube and Package Types
While each payout tube type does not need to use a cardboard box package, each package type is typically named after the tube used, as each payout tube type defines the box construction (top or side-loaded) and how the tube attaches to the package. As a result, the package type is usually referred to based on what payout tube is used.
