I believe the answer is:

rack

I'm a little stuck... Click here to teach me more about this clue!

'stretcher' is the definition.
(I've seen this in other clues)

I can't explain the remainder of the clue.

(Other definitions for rack that I've seen before include "Support" , "Neck or rib of mutton" , "Joint; wine bottle holder" , "Toast holder" , "Place of torture" .)

I've seen this clue in The Globe and Mail.
