Close up look on 2 different base for boltless rack that I have

This is taken in the evening of 26 November 2020. Where my brother no 6 asking me the type of boltless rack base that I used.

The white base is for the one bought with white boltless rack. The black base is to be used with the custom cut boltless rack bought from hardware store.

I really urge my brother to use the base as it helps to protect floor tiles from scratches. Would be better to use wheel with lock. As it is easier to move the boltless rack for cleaning up later.

Till then, have fun in putting base to your boltless rack.
