looking for something like this as i'm trying to hang (so to speak) a fireplace mantel

I know i can make wooden ones.. ( which would be ok for the top part of the mantel) but not for the sides.
does anyone know where to buy these?

as i've searched and i'm comming up blank... ( unless they are called something else)
Thanks

[Pity I had 50 or so strips in my old workshop which got thrown out, could have had them for free.]
Or you could use these.
