I have used an UDD for many years on a CT22 (about 15 yrs old) but recently bought a new CT26. The UDD does not attach to the top like it does with all the other CTs. I have communicated with Oneida about it and they claim their UDD case mold has had no changes and that they have not gotten any complaints similar to mine so no help on the fitment. Any ideas? Pics od CT22 and front view of CT26 showing won't lock down.
