  In this article we consider positivity issues for the clamped plate equation
with high tension $\gamma>0$. This equation is given by $\Delta^2u -
\gamma\Delta u=f$ under clamped boundary conditions. Here we show, that given a
positive $f$, i.e. upwards pushing, we find a $\gamma_0>0$ such that for all
$\gamma\geq \gamma_0$ the bending $u$ is indeed positive. This $\gamma_0$ only
depends on the domain and the ratio of the $L^1$ and $L^\infty$ norm of $f$. In
contrast to a recent result by Cassani&Tarsia, our approach is valid in all
dimensions.
