From a request by Rileys Windows here is a pic of simple tape wrapping that you put on the male sections near the top of the female part that stops the pole compression and locking. Its a few turns that forms a “buffer” to stop pole compression and locking in use, fit once and forget. As the pole wears (yes it does wear) the tape can be removed 1/2" down. Put the pole sections together and wrap at the joint to form a new buffer or stop. Its the blue tape on the nearest section
Hope this helps.
