My first question to you is A: what size mast are you using  both OD and Length 
 B: what antenna do you plan to install ?
 
Why    That top section can be used with the rotor shelf on the top set of 
rungs of the Rohn 25. 
But that's ok if were talking about a C-3,  A-3   TA 33 ect.      but if your 
going BIGGER  the problem comes when it's time to repair or replace the rotor
 
 The little stub  is hard to keep centered by your TB3 ....  if you lower it 
far inside the #25   the cross rungs  can become a problem.
