Orbital elements for a double-lined spectroscopic binary in the intermediate-age galactic cluster NGC 752 are reported. The binary is located just above the cluster main-sequence turnoff, and is a confirmed proper-motion and radial-velocity member. The equal amplitudes of the primary and the secondary velocity curves indicate that the stars have equal masses.
