Wooden rod (5)
I believe the answer is:
dowel
'wooden rod' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for dowel that I've seen before include "Linking peg" , "Peg to hold two pieces together" , "Fixing peg" , "Lowed (anag.)" , "Peg for joining wood" .)
