Abstract

A bouyant hanger unit comprises an elongated body molded of plastic to provide a clip on the bottom end thereof for holding a dental film chip in the plane of the hanger unit. The hanger unit has a circular projection on one face thereof axially aligned with a circular recess on the opposite face thereof. Such a construction enables a plurality of hanger units to be assembled face-to-face while permitting any of the hanger units to be pivoted away from the remaining hanger units in the assembly for the purpose of examining the dental film chip clipped on the bottom thereof. When the individual hanger units or an assembly of the hanger units with dental film chips clipped on the bottom thereof are placed in a solution they float in an upright position with the upper end thereof extending above the surface of the solution.
