Casters add mobility — they let you roll your cabinet out to clean behind it, rearrange your space, or create a more flexible layout. Legs add height with a stable, elevated base, but no mobility. Both lift your cabinet slightly off the floor; choose based on whether you want it to move.

It depends on your cabinet size. A Single Cabinet takes 4, a Double Cabinet takes 6, and a Triple Cabinet takes 8 — and the count is the same whether you choose casters or legs. Just match the set to your cabinet width.

This set is designed specifically to fit Best Craft Organizer Storage Cabinets. If you have a BCO Storage Cabinet, the casters and legs line up with your cabinet's base for a secure fit.

Yes — that's exactly what this set is for. If you originally ordered your cabinet without casters, you can add casters or legs later to give yourself the flexibility to move or elevate it.
