The Fluid Transfer Spring Rewind Bonding Reel provides electrical bonding between refuelling equipment, aircraft and fuel depot sites. 

An internally protected electrical contact is provided which ensures good reliable continuity between the mounting bracket and bonding cable, with a resistance value better than 0.5 Ohms.

A ratchet and pawl mechanism is used to restrain the automatic rewind system while the bonding cable is deployed. 

The ratchet and pawl mechanism requires no lubrication.

Pulling and releasing the cable following deployment activates automatic rewind.  The reel will then rewind at a controlled rate due to the glycerine viscous damping mechanism.  Rewind spring life is also promoted by the visous rewind damping mechanism.

Positive locking of the reel is not required as the spring rewind retains the cable in the retracted position.  

A cable guide acts both to guide the cable into the reel and as a positive stop against a rubber ball fitted to the bonding cable.
