I need to hang up a mirror and two hangers for cloth. All of them have 4 holes each, so I fear I can't mark and drill the holes exactly in the correct places...

So I was wondering if there exist a tool to help with this? I have found a post where someone mentions a "leveler with a slider in the middle", but no mention of what it was called. Searching for "drill guide" also comes up empty in regards to walls.

The mirror is particular tricky as it is 0.5 meter x 1.5 meter, so it is quite heavy.

Question

Does anyone know of a tool that can help one make 4 holes in a brick wall exactly in their correct places?

And if such tool exist, can it support different drill sizes?
