The fixed points saddle of the Fischer massive rail system FMS are supporting elements for securing and accommodating thermal pipe expansion. The massive pipe bracket FMFS UB reliably secures the pipe shoes FMPS and the fixed point saddle FMFS, as well as the sliding element FMFS, to create fixed points or sliding bearings when attached to the mounting profile FMP. The precision of the FMS system elements, achieved through tailored construction heights or spacers, allows for easy fabrication of the required fixed and sliding elements.
