This ratcheting device is used to extend and retract kite lines on the fly.
It is a four line setup with integrated chicken loop and a toggle for ratcheting or release.
Snap shackle pictured not part of original setup.
Outer reels are encased in thin foam shells to aid in buoyancy.
All four reels come loaded with line.
These are not seen in the wild.
This is a little bit of Kitesurf / Kiteboard history.
