Hi, Max. Sorry for the late reply. These aren't intended for floor use, but it could be so long as it's not in a traffic area. If it were somewhere that foot traffic were present, the spring loaded mechanism may break. We do have another grommet that IS intended for use in floors and can sustain heavy foot traffic with heavy duty folding doors - you can find more info about that unit here: http://www.mockett.com/pcs-fg1-4e-94.html

Hope this helps. Thank you!
