The food door clips with snaps are part of the flight data restraint, or bungee system, which is designed to position and retain the flight data charts, maps, and manuals so the crew can view them during the Apollo missions. The system includes long and short data-retention snap assemblies (bungees), long and short data-retention hook assemblies (bungees), Calfax adapter plates, data card clips, data book spring clips, temporary stowage pouches, and a debris closeout with pockets along with food door clips of this type.
The food door clips fasten to the B1 or L3 compartment door. Bungees can be attached to and stretched between the clips for retention of flight data. This clip was transferred to the Smithsonian in 1970.
