Loosen the rubber foot on your pole and remove, then insert the floor adaptor in the bottom of the pole and twist. The adaptor will lock into place. Place a FoamRail tapeless seal on the floor and snap the pole into it. A second FoamRail tapeless seal may be attached at the top of the pole. Complete the seal by raising the pole and setting it in place. Make sure to match the floor adaptor to the size of your pole; adaptors are also available for ZipWall 12 and 20 Poles.
