A slider assembly includes: a front section; a back section, wherein the front section conforms to the cross sectional profile of rails forming the terminal end of a barrier, to which the slider will be fitted; and wherein the front section in combination with the back section create an internal space there between, the internal space dimensioned, to be capable of substantially surrounding both an associated first and second rails of the terminal end, as well as at least two further rails located downstream of said first and second rails, wherein the slider assembly has first and second opposed portions and the slider assembly is configured so that the first and second opposed portions move with respect to each other so the slider assembly applies an increasing compressive force to telescoping rails as a consequence of the slider assembly travelling along one or more subsequent rail(s) during telescoping. |
