Firmly fix length of wood, blue (6,4)

Ross

I believe the answer is:

batten down

'firmly fix' is the definition.

'length of wood blue' is the wordplay.
'length of wood' becomes 'batten'.
'blue' becomes 'down' (I've seen this before).
'batten'+'down'='BATTEN DOWN'

(Other definitions for batten down that I've seen before include "Secure windows, etc, against storm" , "Prepare for a crisis" .)

I've seen this clue in The Telegraph.
