'holes in doors' is the definition.
The answer and definition can be both man-made objects as well as being plural nouns.
Perhaps you can see an association between them that I can't see?

'landlord fights' is the wordplay.
'landlord' becomes 'letter' (landlords let property).
'fights' becomes 'boxes'.
'letter'+'boxes'='LETTER-BOXES'

'for' is the link.

Can you help me to learn more?
