The plates provide a surface with a low coefficient of friction which can be attached to a supporting structure. This combination provides support while simultaneously allowing an object to move (slide) freely along the supporting surface. [1] The plate may be of polytetrafluoroethylene (PTFE),TEF-MET, [2] Lubrite [3] or steel according to the ...
