Assembly instructions

Note that large differences in pullout values can occur depending on old or newly produced lightweight concrete. Lightweight concrete is also produced with different densities that affect the pullout value. The screw-in depth is decisive, the deeper the thread engagement, the higher the pull-out values. Mounted without pre-drilling and with low speeds.
