Court dividers (4)
I believe the answer is:
nets
'court dividers' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for nets that I've seen before include "Meshes to catch fish, say" , "Traps, to catch fish say" , "Brings home" , "Lacy curtains" , "puts ball into goal" .)
