A foot assembly is adapted to be detachably attached to a pole comprising a shaft portion and a ball portion. The foot assembly comprises a foot member defining a first body cavity and a clip member adapted to be detachably attached to the shaft portion of the pole assembly. With the clip member attached to the shaft portion of the pole assembly adjacent to the ball portion, the first body cavity of the foot member receives the ball portion, at least a portion of the shaft portion, and at least a portion of the clip member to detachably attach the foot member to the pole.

A barrier system comprising: at least one pole assembly defining a shaft portion and a ball portion;sheet material;a foot member defining a first body cavity;a clip member adapted to be detachably attached to the shaft portion of the pole assembly;at least one attachment member; whereinwith the clip member attached to the shaft portion of the pole assembly adjacent to the ball portion, the first body cavity of the foot member receives the ball portion, at least a portion of the shaft portion, and at least a portion of the clip member to detachably attach the foot member to the pole; andthe at least one attachment member secures a portion of the sheet material to the foot member. 6. A barrier system as recited in claim 5, in which the foot member defines a second body cavity, where the at least one attachment member is arranged substantially within the second body cavity when the sheet material is held relative to the foot member. 7. A barrier system as recited in claim 5, in which the foot member defines: a longitudinal axis;a first surface; anda second surface; whereinthe second surface is spaced from the first surface along the longitudinal axis;the at least one attachment member holds the sheet material against the first surface when the sheet material is held relative to the foot member;the sheet material is held between the second surface and an object when the sheet material is supported in a barrier configuration; andthe second surface is spaced from the object when the sheet material is supported in the barrier configuration. 8. A barrier system as recited in claim 5, in which: the ball portion defines a first radius that is larger than a second radius defined by the shaft portion; anda thickness of at least a portion of the clip member is predetermined such that the clip member frictionally engages both the shaft portion and the foot member when the slip member is attached to the shaft portion of the pole assembly adjacent to the ball portion and the first body cavity of the foot member receives the ball portion. 9. A barrier system as recited in claim 5, in which: the ball portion defines a first radius that is larger than a second radius defined by the shaft portion; anda thickness of at least a portion of the clip member is predetermined such that the clip member fills at least a portion of an annular space between the shaft portion and the foot member when the slip member is attached to the shaft portion of the pole assembly adjacent to the ball portion and the first body cavity of the foot member receives the ball portion. 10. A barrier system as recited in claim 5, further comprising: a first attachment member; anda second attachment member; whereinthe foot member supports the first attachment member;sheet material is arranged between the first and second attachment members; andmagnetic attraction between the first and second attachment members holds the sheet material relative to the foot member. 11.
