The present work introduces a master action that interpolates between four self-dual models, SD(i), for describing massive spin-4 particles in D=2+1 dimensions. These models are designated by i=1,2,3 and 4, representing the order in derivatives. Our results show that the four descriptions are quantum equivalent through comparison of their correlation functions, up to contact terms. A geometrical approach is demonstrated to be a useful tool in describing the third and fourth order models. The construction of the master action relies on the introduction of mixing terms, which must be free of particle content. We use the helicity decomposition method to verify the absence of particle content in these terms, ensuring the proper functioning of the master action.
