The SB type rail fastening system for tram lines works with pre-stressed monoblock sleepers for R1, R2, 180S and 49E1 tram rails.
Rails laid on the surface of the rail pad between anchors (permanently sunk in the sleeper) are mounted with the SB4 rail clip (or interchangeably with other SB rail clips), which is connected to the anchor from one side, pressing the top of the rail foot on the other side with a spring. In addition, the rail pad is placed under the foot to isolate it from the spring clip and anchored with an electrically insulated hold-down.
