One objection to the use of films in roentgenography has been the difficulty of holding the films in the viewing box.

The outside dimensions are the same as those of the film with which the holder is to be used. Each side and end are from one-half to three-fourths inch wide, depending on the size of the frame and the weight of the material. Across each
