Hi Bill
I've got a Roland piano type sustain pedal that has a piece of rubbery material the same dimensions as the bottom of the pedal that is attached to a screw on the pedal nearest you that swivels so you can put your foot on it to hold it in place. It also has rubber feet on the pedal.
I don't see any model number. Someone gave it to me, so I don't know how old it is or if it's still made.
This pedal is certainly a step in the right direction. (no pun intended)
