Most 10" dobs come with a focuser that has a 2" barrel as standard, so no adaptor is required. Unless for some bizzare reason you wanted to plop in an old style 0.965" ep.
Do you require another 2" to 1.25" adaptor? if so just give astroshop a call.

The Skywatcher DOBs (and possibly Saxon also) have a strange drawtube arrangement which requires (non-standard size) 1.25 OR 2" eyepiece holders. (ie: no adaptor).
Although some newer models may be slightly different now, the (outer) size of the eyepiece holder is slightly larger than standard 2" barrel (On mine anyway), and has locking flanges, so I doubt you will be able to find something that fits properly.
If you do, I'd like to know about it too.
