We observe that the radial gauge can be consistently imposed on-shell together with the Lorenz gauge in Maxwell theory and with the harmonic traceless gauge in linearized general relativity. This simple observation has relevance for some recent developments in quantum gravity where, as we argue, the radial gauge is implicitly utilized.
