I am considering fitting a concealed type door closer, on a lightweight
internal living room door. I notice the room is warmer with the door
closed or almost closed, but often it is left wide open. Its the type
which fits at the hinge edge of the door, completely hidden when the
door is closed and uses a chain and spring to pull the door closed, but
I have never seen one in action.
Are they any good?
Is the 'pull' adjustable?
Does the long part with the spring fit in the frame or the door?
How long is the spring pocket/ how deep would the drill need to go?
If the spring side fits in the door, has anyone found a reliable
technique for drilling deep into the edge of a door by hand, without
bursting through a face due to misalignment of the drill?
A few months ago I replaced 7x internal doors. During drilling for the
latch of one, I managed to burst slightly through the face - luckily
the damage was completely hidden by the door handle.
