I have to put door closers on my doors for my loft conversion. I'm looking at concealed door closers because I dont' want them to be seen, and I've been wondering... With concealed closers, does the concealment have to be in the door? Or can the door jam be drilled to hold the actual unit, and just attach the plate to the door?
Or is that the correct way, and I've just been making a bad assumption that it gets drille dinto the door?
TIA
Hamish.
