Caterers' coffeepots (4)
I believe the answer is:
urns
'caterers' coffeepots' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for urns that I've seen before include "Large pots for tea" , "Runs to find large vases" , "Vase-shaped vessels" , "Burial vases" , "Runs to get large vases" .)
