Building on the PRx Performance Fold-In ONE Rack Beta

Every attachment below is checked for fit against this rack. Add the ones you want to your rack — nothing is saved until you copy it into a setup.

FMTS aggregates fit evidence from specifications, owners, manufacturers, and occasional first-party testing. A fit report documents that parts mate; it is not a certification that a product is safe to load.

The whole rack attachments catalog is on this floor — nothing hidden, nothing re-scored. Your answers build and re-order shelves (they never remove a attachment); shelves start at the lowest price and re-sort your way; only your own filters ever remove.
