The PLUS A fits in between the 1st and 2nd section of the Reach-iT MINI.
PLUS A (compact height 4ft 6") is an 8ft 4" extension which, along with PLUS B, extends the MINI to 45FT, or 55ft reach!
PLUS A is a Core Rigidity Extension. The taller the pole is, the more stress gets applied to the middle sections of the pole. Adding a high modulus extension increases the rigidity at the core while extending the reach of the pole.
With the CONNECT AB, you can turn PLUS A (and other PLUS B extensions) into a second 25ft modular water fed pole.
