Artist's tripod (5)
I believe the answer is:
easel
'artist's tripod' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for easel that I've seen before include "Wooden frame for an artist" , "Constable's stand?" , "Stand used by artists" , "Artist's canvas suppot" , "A stand for blackboard or artist's canvas" .)
