65mm cassette spool set

This is a set of two matching Mercury 65mm spools.  They can be inserted directly into standard 70mm metal cassettes.  A pair of these come free with every Mercury back available on this site.  If you wish to use your own back or purchase extras, this is the item! Note that these accept Kodak's original metal retaining rings, but do not come with them.  Use blue painter's tape to thoroughly fasten 65mm film to these spools when loading, even if using a metal retaining clip. We have several variants, to cover all 70mm backs: Centered: These spools perfectly center the 65mm film.  They are for use with all Mercury modified backs (medium format or large format) sold on this site, as well as original Graflex RH-50, Linhof Cine Rollex backs, and Mamiya 70mm backs.   Offset:  These are like those above except that they offset the 65mm film slightly to enable it to make contact with the spacing wheel on Hasselblad A70 backs. Max Offset:  70mm backs for 645 cameras (Bronica ETR and Pentax 645)
