My different 3" spools are different diameters. I have about 8 different rings, 4 different sizes made in pairs, that I use. Some situations call for a single paper for a good fit. Some situations need two.

Easily ran a few thousand kilos through it so far and haven’t had to touch the seals yet, inspected them last week. I purchased a spare full rebuild kit when I got the unit, for back-up, but its been sitting collecting dust.
