He does have a good point though.
We opened this can of worms a few months ago and im not sure what the outcome was.

I have an electric lifter which had covers over the sharp edges, in terms of a safety bar to physical stop it from moving i think it wasnt needed as the lifter was electric, the Removable Link was good enough as the lifter would not move without the link.

So i dunno what the answer is, maybe someone from the FRA wants to confirm the answer, but i know Big Nipper, Storm 2, myself which electric lifters have not needed a safety bar to stop it from moving. But safety covers to cover sharp edges yes as always.
