Support that often comes with ruin (4)
I believe the answer is:
rack
I believe this clue is a double definition.
'support' is the first definition.
(I know that rack is a type of support)
'that often comes with ruin' is the second definition.
(as in the phrase 'rack and ruin')
(Other definitions for rack that I've seen before include "Shelf for luggage" , "Storage frame; draw off (wine)" , "Luggage carrier - instrument of torture" , "Neck or rib of mutton" , "Rail for torture" .)
