Bakery fixture (4)
I believe the answer is:
oven
'bakery fixture' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for oven that I've seen before include "Cooking appliance" , "Chamber for baking" , "Compartment for heating" , "Liquid oxygen; salmon" , "Cooker; furnace" .)
