I have a small wheel( 2" diameter x a little less than 1" thick ) that fits into a small box and is flexible to move up and down. Do you have a spring-like bracket for the wheel and something to hold it tightly in place in the box when it is not needed to be lowered for use?
Your 84-086 seems appropriate from the photo, but does it have something to keep the wheel up when not in use?
Thank you for your time and effort in assisting,
Dale
