First, losen the rubber foot of the pole and remove it.
Make sure the floor adaptor you are using matches the size of your pole.
Insert the floor adaptor into the bottom of the pole and twist to lock it in place.

To seal a barrier at the floor, place a FoamRail™ tapeless seal on the floor, and snap the pole into it. You may attach a second FoamRail™ tapeless seal to the top of the pole. Raise the pole and set it in place to complete the seal.

Floor adaptors work with all FoamRail™ tapeless seals.
