Tell sir about the climbing frame (7)

Ross

I believe the answer is:

trellis

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

'climbing frame' is the definition.
'trellis' can be an answer for 'frame' (trellis is a kind of frame). I am not sure about the 'climbing' bit.

'tell sir about' is the wordplay.
'about' indicates an anagram.
'tell'+'sir'='tellsir'
'tellsir' with letters rearranged gives 'TRELLIS'.

'the' acts as a link.

Can you help me to learn more?

(Other definitions for trellis that I've seen before include "Lattice structure" , "supporting frame" , "Train for plants" , "Framework - stiller (anag)" , "Framework for creepers" .)
