We had one fitted for MIL on one of the staircases, two rails with quite complicated curves. It hasn't been used since she died a few years ago, I am inclined to leave the rails in place but it would be nice to remove the chair, until next required.
They seem to be cunningly designed so that only their approved contractors can work on them (e.g. I'm buggered if I can see how to get the batteries out to replace them).
I thought at first that the seat might "lift off" after removing the constraints, but it looks to me as though you might need to wind it off at the top, after removing the fairly simple "stop". Anyone know if this is correct?
I've made a tool so that I can hand-wind it with a brace (and possibly with the cordless drill) but before I take it up to the top it would be nice to confirm if this is the way it is done. Otherwise I could see myself ending up with a landing and stairwell full of ping-fuckits.
