Abstract: If

is a triangular $2\times 2$ matrix ring, the columns

and

are f.g. projective

-modules. We describe the universal localization of

which makes invertible an

-module morphism $\sigma:P\to Q$ , generalizing a theorem of A. Schofield. We also describe the universal localization of

-modules.
