Let T  (Y, ) be a transverse knot which is the binding of some open book, (T, ), for the ambient contact manifold (Y, ). In this paper, we show that the transverse invariant bT(T ) 2[HFK(−Y,K), defined in [LOSSz09], is nonvanishing for such transverse knots. This is true regardless of whether or not  is tight. We also prove a vanishing theorem for the invariants L and T. As a corollary, we show that if (T, ) is an open book with connected binding, then the complement of T has no Giroux torsion.
