Modules in which every essential submodule contains an essential fully invariant submodule are called endobounded. Let M be a nonzero module over an arbitrary ring R and X = Spec 2 (MR) , the set of all fully invariant L2 -prime submodules of MR . If MR is a quasi-projective L2 -Noetherian such that (M/P )R is endo-bounded for any P ∈ X , then it is shown that the Krull dimension of MR is at most the classical Krull dimension of the poset X . The equality of these dimensions and some applications are obtained for certain modules. This gives a generalization of a well-known result on right fully bounded Noetherian rings.
