Slidable barriers

A system comprising:

• a structure having a plurality of stories;
• a first retainer element operatively connected to the structure, the first retainer element spanning a plurality of stories of the structure, the first retainer element including a plurality of retainer segments, the plurality of retainer segments including an uppermost retainer segment and one or more lower retainer segments, the one or more lower retainer segments including a lowermost retainer segment;
• and
• a barrier, a portion of the barrier being retainably engaged by the one or more lower retainer segments of the first retainer element, the barrier having an associated length, the length of the barrier substantially corresponding to a length of the lower retainer segments, the uppermost retainer segment extending vertically above an upper edge side of the barrier.

A slidable barrier kit for use in connection with structures having a plurality of stories, the kit comprising:

• a barrier, the barrier having an associated length, the length of the barrier substantially corresponding to a number of stories (n) of the structure;
• a first retainer element, the first retainer element having an associated length, wherein the length of the first retainer element corresponds to n+1 stories of the structure, the first retainer element including a plurality of retainer segments, the plurality of retainer segments being substantially identical to each other;
• and
• a second retainer element, the second retainer element having an associated length, wherein the length of the second retainer element corresponds to n+1 stories of the structure, the second retainer element including a plurality of retainer segments, the plurality of retainer segments being substantially identical to each other.
