One Bolt Swivel Caster Mount for Ikea Bror Shelf

UPDATE (12/04/2024): I've been using these caster mounts for about two months now with about 125 lbs. of weight on the shelf, and so far they have held up well. I have attached two pictures of the shelf with casters in use just so you can get an idea of how they are currently being used.
