Building on the FringeSport The Fenrir Functional Trainer & Squat 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 build.

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.

Ranked from your picks — commission never affects order · How this works

See the floorspace it needsBeta

This marks out the space the FringeSport The Fenrir Functional Trainer & Squat Rack claims — its published footprint and height at true size, like taping off the spot in your garage. It shows the room it needs, not the machine itself.

Point your camera at the floor once it opens.

Snap a photo in AR and post it — tag @flex.marks.the.spot and we'll share our favorites. Living-room racks welcome.

Floorspace footprint Floorspace only — the maker's published footprint marked out on the floor at true size. Not a 3D model of the machine: this equipment's shape can't be drawn honestly from its published numbers, but the floor it needs can. 49.5″ × 47″ of floor · 87.5″ tall.
