I know a subject such as this is going to get 'humorous comments, and consider it put there for those that must.
I have a hardwood rack that currently has 2 cross rails aprox 3" wide by
24" long that rest on the floor. to allow for better stability when on less than perfect floors ... it would make sense to put some rubber feet on the outer edges, so that only the end actually touches the floor ... looking for some rubber (ish) material that has a little give so that it will sit on uneven ground ... but not too soft due to weight of rack.Ideally something like 3" x 3" squares .. 1/4" or so thick ..... any ideas ?
I tried FleaBay .. loads of stick on feet .. either too small or way too thick.
