Stage front (5)
I believe the answer is:
apron
'stage front' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for apron that I've seen before include "Kitchen garment or aerodrome strip" , "Protective garment - type of stage" , "Domestic protection" , "conveyor-belt" , "Paved area where aircraft are parked" .)
