A Su-Schrieffer-Heeger model with added PT-symmetric boundary term is studied in the framework of pseudo-hermitian quantum mechanics. For two special cases Lambda=0 and gamma=0, a complete set of pseudometrics P-(k) is constructed in closed form. When complemented with a condition of positivity, the pseudometrics determine all the physical inner products of the considered model.
