Tubes
Body tubes hold the battery holder/batteries and attaches to the flashlight head and acts as the flashlights handle/grip. When empty, body tubes serve as a water-proof storage capsule good for storing any parts or accessories. Use flat caps or carabiner caps to secure the internals from water or dust. Like most of the ZeroHours external parts, these are nearly indestructible and made from 6061 aircraft-grade aluminum.
