I'm surprised you can't find an anchor big enough for those holes. Can you move the fixture an inch or so sideways one way or the other to get fresh mortar and still hide the holes?

 

Are you trying to use the large mortar holes to install bolts that will come out through the fixture and just install finish nuts on them, or are you using a mounting bar/circular base plate that comes with light fixtures ?


There should be a box for the fixture, but it will be a bear to cut one in to those stones. And a surface mount box will be UUUUglly.....

 

My other question is should these wires be in a box with a mounting ring attached or are wires coming right out of the brick like that okay?

 

A mounting bar came with the new light, but there was no circular plate being used when I took the old light down. Not sure if should be installing a circular plate first or just mounting back directly on to the brick?

 

The round mounting ring will help with the installation IF YOU have the two bolt mounted fixture and not the one with the single lampart going through the center of the light with the acorn nut on it. The round base plate is shown in pic, but only works if you have the two bolt fixture that matches the 8-32 bolt pattern holes shown. JMO

 

Cut a live twig or stick just slightly smaller then the hole. Then trim it flush and install a screw. It works really well. It won't come loose and will last as long as you need it to.

 

I think you should try another hardware store, you should be able to find what you need. There are all kinds of wall anchors out there. Worst case if you can't, find some filler material (wood, hard plastic, etc) and glue it in there and then use wood screws to hold the light up.

Ayuh,...... Why not just pack the holes with mortar, let it set-up, 'n then drill whatever sized holes ya want, where ever ya want 'em,..??..??

 

I almost suggested that Bondo and you may be right that may be the easiest way to do this. The only reason I didn't say that is I am not sure if a small area of concrete patch would hold up to drilling, might just crumble was my thought. On the other hand, my suggestions may just crumble as well.

 

This is what you need, hardware store or a box store will sell them individually.
