You will need two poles, A. B. Remove the B x 3rd section with the clamp in tact, from pole A .
This will be the extension for pole B.
Now you need to join the 2 sections
This you do by using one foot of pole A second section and putting it up pole B and fastening it with epoxy glue and pop rivets. This one foot section must not go into the B pole by more that 6 " NOW ADD THE THIRD SECTION OF A TO POLE B .
iF THIS HELPS
yOU WILL NOW BE ABLE TO CLEAN SECOND FLOOR WINDOWS.
The left over sections one and part of section 2 will make a good short pole from ground floor. I still use mine after 6 years. I hope this makes sense.
