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><span style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>Cheers, Joe <o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><div><div style='border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal><b>From:</b> Lerftest [<a href="mailto:lerftest-bounces@jlab.org">mailto:lerftest-bounces@jlab.org</a>] <b>On Behalf Of </b>Joseph Gubeli<br><b>Sent:</b> Tuesday, January 30, 2018 11:05 AM<br><b>To:</b> <a href="mailto:lerftest@jlab.org">lerftest@jlab.org</a><br><b>Subject:</b> [Lerftest] LERF Gallery Raised Floor<o:p></o:p></p></div></div><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><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Thanks, Joe<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><span style='color:#44546A'>Joseph F.
