Problems fitting steel channeling

[thespaceman]

I'm having real problems securing steel channeling to a brick wall. I've chiseled out a 1.5" channel in the brick and was wanting to cover with steel channeling. The capping nails are splitting the brick either side of the channel and the nails don't hold. Same goes for the mortar as well.

Any ideas how I can get round the problem? I was thinking of going for a wider channel but think 1.5" is the widest. I've seen wires covered by a gulvanised sheet of steel but don't know where to buy this? Any advice welcome!

Or forget the capping, and put oval conduit in the chases.

LOL ok fair point. I'll fit it with screws and plugs and whatever that yellow thing is!

I would have used round conduit pipe as I have some spare but I had to run a few cables including a scart cable which is obviously too big to fit through.

Cheers
