[3a] INSTALLATION OF WK TYPE
When mounting MODEL 096 arm bracket, the wall and the strength of the hardware used must be
checked and veried as being adequate to withstand a 45 kg shear load and 200 kg withdrawal force
at each of the three mounting bolts. When using concealed wiring, a ush mounted junction box
with the necessary conduit and wiring must be pre-installed at 113 cm from the oor.
