I am currently wiring up a new residential home. The home owner wants sconce lights on the exterior. House will be brick. I have not wired up a house with brick exterior, always been siding. How do you typically set the light boxes? Have the brick masons set the boxes while the brick is going up? Chisel and set the boxes later? Will also be using the arlington flush mount for exterior receptacles too.
 
You can use one of these:

Just used a case of deep ones of that type on an all brick kitchen. As others have said, stub the wire and box out where it goes, and the brick mason will get it in the run. It is also good to communicate with the brick mason the approximate height. Be sure to duct tape the opening if you don’t want it full of mud! LOL!

Just in case it's not obvious, make sure you bring the cables in through the back of the box.

Drill a hole through the sheath at the exact spot you want your light to be placed, and leave only 6 to 8 inches of cable hanging out. That forces the brick layer to have it reasonably close to where you planned it.

Also don't forget to install the 8-32 bonding screw before placing. There's a good change the back of the box will be embedded with cement.
 
Actually, I prefer plastic boxes to metal for embedding. With a standard nail-on, I push the nails halfway in, which leaves four anchoring points.

No grounding, no rust, no stuck screws, and bigger screws can be used more easily if the holes ever become stripped.
 
We have had instances here where the masonry boxes, having 6-32 screws, were not accepted as suitable for fixtures exceeding 6lbs. (314.27).
Has anyone encountered that situation ?

It could be a technical issue but I don't see why. A metal box embedded in brick and mortar will be stronger than one mounted behind drywall. If the problem is the 6/32 screws then there should be an allowance (currently there isn't) to use 8/32 or larger screws. Usually for larger fixtures you end up screwing part of the mounting plate into the brick because it's part of the instructions. Here's one I recently installed where the plate was large enough to attach directly to the brick and the metal box.

You could always tap out a metal box to allow for 8/32 screws too.

Be thankful if you get anything out of Arlington. I'm told if they have it in stock they'll ship it. If not, they won't take an orders for future shipments. Not sure if that's changed recently though.

I've used these boxes before and they fit great in the brick line. The problem that I have with this type of installation is that the canopy of the fixture will not sit flush on the brick or mortar line and bees will get in and nest behind them. The other thing is that those threaded studs that are sticking out may extend too far beyond the face of the canopy and you'll have to drill out the brick so that they'll recess into the brick. But, nobody said that hanging a light was going to be easy :cool:

I've been buying up Arlington stuff on eBay. I don't know what they actually have on the shelf in their warehouses, but clearly its nothing I actually use.
