By slotting into the horizontal rail, keying blocks can be positioned in front of guide rails of the type Accessory or Strengthened. In conjunction with IEL/ IET handles and coding pegs a keying in accordance with the IEEE standard can be established. Like the new guide rail generation also the new keying blocks are produced out of a high quality plastic material with improved fire safety properties. Which means the material ensures a low flammability, low smoke toxicity and density and fulfills the EN 45545-2 (Fire Safety in Railway Vehicle) requirements sets R22, R23 and R24 with the highest hazard level HL3. In addition the keying blocks are also considered as “Halogen-Free”, according to IEC 61249-2-21.

Please order IEL/IET handles and coding pegs separately.
