I would have expected metric dimensions, but the first measuring instrument I found was in inches, and the measurements look right on. Base footprint is 2 3/4" x 2 7/16"; the tall side is 1 11/16" and the central "handle" is 1 5/8".

The take up roll turns freely; the feeder will turn forward but not back. It should work for your purposes.

These measurements are from a 120 holder, but I think the 220 holder is the same in these outer dimensions.

Anything else you need?
