Box-form enlargers consist of a box often pyramid shaped, a negative holder at one end, a paper holder at the other and a lens in between. They were often called Daylight enlargers which was the normal illumination though magnesium (flash), gas light or electric could also be used. The scale of enlargement was generally fixed. Some models could take two negative sizes with two corresponding paper sizes. Better models were fitted with dark-slides to hold the paper others had to be loaded in the darkroom. A simple shutter is often present.

This was for use with the Block-Notes camera. The negative carrier is removable. The dark-slide has a removable panel to load the paper and resembles a wet-plate slide.

This was for use with the Verascope camera. The top, brass section, holds a lens and simple flap shutter.

The body dismantles and collapses for storage.

The Helinox was introduced for use with the Baby Ikonta and other 16 on 127 cameras. Shortly afterwards a model for 35 mm was introduced. The 3 x 4 cm size came in two models for either 3 ½" x 2 ½" or 9 x 12 cm prints. The 35 mm models were for either 3" x 2" or 9 x 12 cm prints. Postcard paper could be used with the 9 x 12 cm models. The normal bulb was 40 or 50 watts. The lamphouse could be removed for daylight use.

An electric lamp attachment (cde 1410/11) could be fitted.

Also produced for postcard prints from 2 ¼" x 3 ¼" negatives. Unusual red/mauve finish.
