We have investigated the exclusive, radiative B meson decays to K{sub 2}*(1430) in 89x10{sup 6} BB-bar events with the BABAR detector at the PEP-II storage ring. We measure the branching fractions B(B{sup 0}{yields}K{sub 2}*(1430){sup 0}{gamma})=(1.22{+-}0.25{+-}0.10)x10{sup -5} and B(B{sup +}{yields}K{sub 2}*(1430){sup +}{gamma})=(1.45{+-}0.40{+-}0.15)x10{sup -5}, where the first error is statistical and the second systematic. In addition, we measure the CP-violating asymmetry A{sub CP}[B{sup 0}{yields}K{sub 2}*(1430){sup 0}{gamma}]=-0.08{+-}0.15{+-}0.01.
