Hi experts,
Did anyone ever install a Nortel Doorphone on glass surface? As you know most of the commercial units are having doors with aluminum framed glass door.
As for a Panasonic doorphone, we can use some commercial graded glue to stick it on, as it comes with a flat base where we can apply the glue; but it seems harder for a Nortel one as the base is hollow inside...
Any idea? Help!

Don't know.

But how about mounting it to wood or even a nice piece of thicker plastic. Then super-glue it to the glass.

What are you doing with the cable ??
Just wondering.

I wouldn't use wood as it would look like crap from the other side, but agree with the plastic.

I'd mount it right next to the frame to reduce wiring visibility as much as possible.

Hey, clients have to understand we're not miracle workers!

Thanks for the advices!
I don't worry about the wiring, just like what MooreTel said that we'll normally mount the doorphone as close to the hollow metal door frame as possible in order to have better appearance and security; still it is not 100% secure, as there might be still 1/8" cable can be seen normally.
Yeah, I found some installers came up with a nice piece of wooden block painted with black or so, and being a buffer in between the glass surface and the doorphone, they must be tailor-made by themselves.
Plastic is a good idea too, but seems even harder to find one, any idea where to find it?
Do you think using silicone/caulking as the adhesive and spread it along all the edges would be strong enough to do the job? Anyone went down this route before?

I've used 1/8" nipples for light fixtures in finishes like pewter to conceal the wire between the frame and the unit in the past. I've also used chrome toilet supply tubes for these situations.

I get black 1/4" thick plastic from a local sign shop. They usually just let me take scrap pieces from their recycling bin and they'll cut it for me.

Funny, I've come up against that situation myself recently. I ended up positioning the doorbox plastic frame adjacent to where the wire came out of the metal window frames and just placing a silicone cauking bead on the window. I waited for it to set up/harden before installing the extra weight of the doorbox (electronics) in the unit and I've never had a recall or complaint from the owners. On the inside of their lobby, I had taped off the cauking line to keep it even looking, but they posted a sign on the window to hide the back of their doorbox, so no problem. I imagine if a vandal wanted to pull it off he probably could but it's on their good.
