We consider inhomogeneous matrix products over max-plus algebra, where the matrices in the product satisfy certain assumptions under which the matrix products of sufficient length~are rank-one, as it was shown in [6] ({\it Shue,\,Anderson,\,Dey 1998}). We establish a bound on the transient after which any product of matrices whose length exceeds that bound becomes rank-one.
