As in the product description 2" Deluxe Clamp / Eyepiece Holder for SCT's with 2" SC female thread I am not sure this item would fit your T2 Diagonal as the Eyepiece Holder apparently has a SC thread and not the T2 thread you require. You may need a Baader T-2 to SCT Thread Expanding Ring to get the Eyepiece Holder to fit.
