Hi Cheshire,
The problem I have, is if we rely on customers to source there own parts, then if it does not go to plan, we as a company get the blame.
it's like the piece of hose you get with the kit, it is stretchy hose which you need for it to work.
the sleeve ejector need to be able to be pulled out the base to release it from the pole.
you cannot use pvc hose to do this as this time of year it goes to hard to stretch. If you buy the kit and don't diy then you buy hassle free setup, with full instructions.
Steven.
