They are made in a variety of sizes. One of mine, suit length, is long enough for 135, though I no longer use it (or 135). I don't "wipe" film, roll or otherwise, inside or out of drying cabinet. PhotoFlo and that's it (distilled water rinse only for sheet). If you don't want to loop a roll, cut it and hang the sections. That will have to be done eventually anyway, unless you're processing movie film.
