  The hybrid mesons form a part of the exotic spectrum of the standard model.
The recent observation of the isoscalar hybrid, called the $\eta_1(1855)$,
provides an important step towards the completion of the $1^{-+}$ nonet. In the
present work, we analyze the masses and two-body decays of the members of this
nonet using a model hadronic Lagrangian. The isovector $\pi_1(1600)$ has been
studied extensively - both experimentally and on lattice. We use the available
experimental and lattice data to extract the coupling constants. Using these
parameters, we analyze the possible decay channels for the hybrid kaons.
