Abstract
A slider assembly including a front section, and a back section, where the front section is adapted to conform to the cross sectional profile of rails forming the terminal end of a guardrail, or other barrier, to which the slider assembly will be fitted in use. The front section in combination with the back section create an internal space therebetween capable of substantially surrounding both an associated first rail and an associated second rail of the terminal end, and at least two further rails located downstream of the first and second rail. The slider assembly includes first and second opposed portions configured to move with respect to each other so the slider assembly can, in use, apply an increasing compressive force to telescoping rails as a consequence of the slider assembly travelling along one or more subsequent rail(s) during telescoping.
