<p class="MsoNormal"><span style="color:#1F497D">Please ignore
the L bracket method to prevent grating slip. A better
approach would be to add rods to the bottom of the grating
that would fit into oversized hole in the top of the
channel. The connection to the floor would be just through
the bottom flange. This would allow for a smooth channel top
during cable installation. I’ll send out an image later.<o:p></o:p></span></p>

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The images below are, in general, what I
imaging the raised floor will look like behind the SSAs. The
grating is 1” x 3/16” (18” x ~34”) aluminum with a safe load
of 632 lbs per square foot for a 24” span, our unsupported
span is 15”. The channel is 6061 aluminum 4” x 1.58” x 0.18”
anchored to the floor with ¼-20 bolts spaced 18” apart. The
“L” brackets will keep the grating from sliding much. More of
this raised floor could be added to extend to penetrations.
Let me know if there are a questions or comments. <o:p></o:p></p>
