Artist's tripod (5)
I believe the answer is:
easel
'artist's tripod' is the definition.
(I've seen this in another clue)
This is all the 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" .)
