Ping-Pong table dividers (4)
I believe the answer is:
nets
'ping-pong table dividers' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for nets that I've seen before include "practice area" , "Brings home" , "Meshes to catch fish, say" , "Captures" , "Cricket practice venue" .)
