Film reel (5)
I believe the answer is:
spool
'film reel' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for spool that I've seen before include "Loops around with reel" , "On which film is wound" , "Loops around a thread holder" , "Film reel; wind" , "Cylinder for winding film etc" .)
