DTi to Feature Transit & Rail Series Grommet Edging at RSSI Minneapolis

DTi Spring-Fast® SL-FST is EN 45545-2 and NFPA 130 Compliant and Available for Immediate Shipping

Southborough, MA September 20, 2019 – Device Technologies, Inc. (DTi), a leading manufacturer of wire protection products, will be exhibiting at the 59th Annual Railway Systems Suppliers Inc. (RSSI) C&S Exhibition Sept 21-24, 2019, at the Minneapolis Convention Center, Minneapolis, MN. Located in Booth 4524. DTi will be featuring their new Spring-Fast SL-FST Transit and Rail Series, the latest addition to its successful Spring-Fast Wire Protection Grommet Edging family of products. Spring-Fast SL-FST is a universal solution for US and Eurozone wire protection markets and is EN 45545-2 and NFPA 130 compliant.

All materials used in rail vehicles must follow the EN 45545-2 standard in order to achieve the highest level of safety possible in the event of a fire. This standard affects manufacturers of rail vehicles including high speed trains, regional trains and trains in industrial transportation.

Nick Petri, Managing Director of DTi commented, “Until now, limited options have been available for a universal solution for both the US and European marketplace compliant to EN 45545-2 Railway Standard for Safety. DTi’s SL-FST is a universal solution that meets this demanding standard.”

DTi’s SL-FST series is the fastest, safest, most reliable way to protect wires, cables, and tubing from abrasion. It can save 49% of the installation costs of grommets and glue because it locks on with finger pressure in seconds, eliminating solvents, adhesives, ancillary materials, and volatile organic compounds (VOC’s) while installing in half the time of traditional nylon grommets. It is ideal for demanding Transit and Rail applications and meets the strict testing requirements of EN 45545-2 and NFPA 130. SL-FST is fully encapsulated in a flexible non-halogen, flame retardant, low smoke, low corrosive, and low toxic thermoplastic compound for added abrasion protection.


  • 49% Cost savings (installs for half the cost of plastic MS21266)
  • 9.5x Productivity increase
  • Highest standards of performance
  • Improved safety – no toxic adhesives/solvents


  • Eliminates installation adhesives and cleaning solutions while improving productivity
  • RoHS and DFAR compliant
  • Multi-axis flexibility for flanged holes, inside and outside corners
  • Indoor and outdoor use
  • Continuous edge protection
  • Excellent resistance to abrasion, water absorption, and low and high temperatures
  • Improves ergonomics during assembly
  • Tested according to IEC, EN ISO and ASTM standards and requirements for flammability, cone calorimeter, toxicity and smoke density.

In addition to use on railway vehicles and control systems, the SL-FST can be deployed in a variety of other high-performance applications such as aircraft interiors, avionics, medical equipment, telecom and defense vehicles.

SL-FST is available for immediate shipping. For more information on specifications and ordering options, contact DTi subsidiary DTi device technologies GmbH at:
