I am installing a PLCM-UNL-CP in an office building with a drop ceiling. The ceiling above the acoustical tile looks and feels like metal and i would assume concrete above the metal.

There will be a 5' extention pole and a 60" samsung.

I was hoping to use 4 tapcons and call it a day. I think i might need to use sleeve anchors. Any suggestions..

Thanks!!

I wouldn't assume ANYTHING about that ceiling.

Check with the building engineer to ENSURE it is NOT a post tensioned slab.

Also make sure to check with the building engineer to make sure that there are no pipes conduits in the area you want to drill.

I wouldn't rely on tapcons, go to your local fastenal or atleast use some epoxy sleeve anchors. Tapcons dont have a very high pull out strength

Not any type of support under the steel?

How are the ceiling and lights mounted?

I was just wishing there was a like button for this post. There's got to be some steel beams up there somewhere. And maybe it is just me (having watched a tube TV fall from an installer putting a sleeve in backwards), but I never use those crappy sleeves and lag bolts.

I have done this before.

One way was to get a plate, about 6" x 24," that fits into the tbar frame. It's got a movable panel for putting the pole exactly where you want it. That panel locks down. You add TBar support wires to the four corners of the mount. At least one of these goes up and four should go up at 45 degrees for earthquake support.

Another way was to install unistrut from existing structure, then hang from that. Tie wires also go up at an angle for earthquake support, too.

Unfortunately there is little to no space above to work. There are a/c ducts in the way. I spoke to the contractor about this and he told me there are no pipes or strings. The contractor shot into this same structure to hold the ceiling and electrical.

Is there steel trusses above the ceiling? If so, this is the best way to rig it. Run 2 unistruts spanning 3 trusses if possible. Clamp the unistrut to the trusses with these: [Link: bing.com]
Mount your poles to the 2 struts at your location and you're good to go

Although unistrut would be ideal, it doesnt sound like you have the space or the structure to attach it to.

I would mark the location of the mount, mark the area and see if the general contractor onsite is willing to drill the holes for you, have a case of beer ready to give him!

Well, went out today. Spoke with the contractor and again he assured me that I can drill into the structure..He also said that tapcons would be sufficient. I ended up using 4 tapcons. I had Redhead sleeve anchors as a back up if I did not feel the tapcons had a good grip. the only issue I had was the complaint of noise from the floor above. They wanted me to come back after hours to drill.. I was on the last hole...

Job done!!

Ernie are you talking about the CMJ500R1? That's exactly what I was thinking of until he mentioned a 60 inch Samsung. I've only hung projectors on this mount, but i think it would be a great solution if the tv, drop pole and brackets on the back of the tv weigh less than the 60 pounds the specs say it supports.

I wouldn't have felt comfortable leaving that job after using tapcons. Over time, tapcons have the tendency to loosen, especially with pull-out strength.

You should have used the sleeves or bought long enough wedge-anchors to mount a plate directly to the concrete.

hopefully, it's not a high traffic area underneath the TV.

a agree with the tapcons loosening over time. However, I felt how they went in and the grabbed hard.. I also hung from the mount and feel it is very solid. I would have used at least 2 sleeve anchors, but the drilling was an issue. If I did not feel 100% I would not have done it with the tapcons.. And yes, no traffic!!
