  We present a catalog of 80 very wide fragile binary candidates (projected
separations > 10000 AU) from the SDSS DR8 spectral archive. The pairs were
selected based on proper motion, radial velocity, metallicity and photometric
parallax criteria. The angular separations of these pairs range from 3" to
250". The peak in the metallicity distribution of these pairs is about -0.5 dex
of solar metallicity. Space motions and reduced proper motion diagrams indicate
all these pairs are members of the disk. The chromospheric activity index SHK
of each component in 38 binary candidates having spectra of high
signal-to-noise ratio and member stars of three open clusters (NGC2420, M67 and
NGC6791) were measured. The SHK vs. color relation for these binary candidates
is consistent with the trend seen in these open clusters. The ages implied by
this relation suggest that fragile wide pairs can survive longer than 8 Gyr.
