Two versions the first is for 2" to 1.5" and the second is 1.5" to 1"
Based on Walter Monkhouse's design for the ASAP Sr found here: http://www.magicchristmas.org/uploads/3/4/6/9/34698654/asap_sr_two_stage.pdf
Disclaimer: Due to inconsistency in pipe O.D. or oxidation on pipe, please verify that
the bushing slides smoothly before erecting the ASAP Sr. pole. You may
need to sand the pipe lightly with a scotch bright type of pad.
