Abstract
A device for supporting a strip of photographic film and for preventing the same from curling during the drying step of developing thereof. A body portion is provided with at least one pair of hook members extending from an edge thereof. The hook members are arranged spaced apart on said edge to enable them to pass through and be positioned within the sprocket holes adjacent end frames of the film strip. One such device may be positioned at the top of a strip of film to support the same on a hanging line or pin for drying; a second device may be positioned at the bottom edge of the film strip to prevent the same from curling during said drying of the strip.
