"Totem" detail gebraucht

Hello everybody and please excuse me for not using German.
I must make a shop list for stone cladding at a new residential building. At the entrance we have a "totem" - decorative wall clad in slate stone. At the very top of the "totem" wall i need some capping, a stone plate maybe with weepers on both sides, maybe not. Could you please help me with any detail?
Best regards,
Dan Stroescu
