I would like to run a 3/4" copper pipe on an exterior concrete wall and have the pipe be mounted such that it stands off the wall for more or less an inch.

What is the best way to mount it?

(1) I see these bell shaped clamps, secured with one screw. Since it's concrete wall, I could not use the metal screw but need to use something else such as Tapcon screw. My question is whether this can be used outdoors where it rains a lot. It looks copper but it's actually copper "plated" steel.



(2) Then there are these split ring brackets. You mount a base (usually two screws), then a threaded rod, then the split ring. It's not clear to me if this would be a tight fit, or will it be very loose since this seems to be more intended for indoor ceiling mounting? Again not sure if I can use this outdoors, but may be there are stainless steel version of this.



(3) I could also use those unistruct channels with pipe clamps. Seems an overkill though.

(4) Finally I could use strips of 1X PT lumber mounted on the concrete wall, then use regular 3/4" two hole straps with regular ACQ rated screws.

Thoughts?



Edited 1 times.

I would use 6" lengths of zinc plated 1 5/8" strut along with cush clamps.

Use two 1 1/2 x 1/4" tapcon concrete anchors with fender washers.

The cush clamps are ideal when working with copper pipe because until you fully tighten
you can twist or side the copper pipe as needed.

Of course, copper pipe, being rather soft, is not suitable for exposure to children's recreation or even adult renters. My rental is finally completely repiped from galvanized to copper and pex, except the exposed hose bibs and sprinkler manifolds. These will remain galvanized since I discovered steel gardening tools hanging from one.

I've used the Touch Down bracket by Soiux Chief with good success. I did not use them outside, description indicates it is UV rated.

I used them with noise reducing inserts which I think gives it about a 1/2" to 3/4" stand off.

You could use a piece of copper pipe between wall and bottom of bracket to increase standoff.

Just a idea.

I also made a all copper bracket with copper cap as the standoff,brass screws and copper pipe straps for 3/4" copper condensation drain line in a high end rustic wine cellar. Bit of a pain, but it worked. I will be at job site next week and see if I can get a picture.
