This is NOT for a 114mm scope! I made that mistake and was unable to return it.
The inner diameter is a bare 114mm. Therefore, this is for a scope that has the outside diameter of the object end is under 114mm.
I would guess that it is good for many 90mm and 102mm scopes.
Please measure your scope before buying. I will not accept a return.
