Construction Polymer Technologies produces the Resilient Fastener (RF), a high-performance Pad/Plate fastener system, as well as the Delkor Rubber Bonded Rail Fastener system (DF). Both fastening systems are produced in the United States and are Buy America compliant.

The RF’s bottom plate is a fabrication so the anchorage positions can be custom configured to a customer’s requirements, while the top plate can be produced as a fabrication to accommodate the use of different rail hold-down clips, rail sections, and canted or non-canted rail seats. The RF system includes a line of resilient fasteners for use with guard rails, restraining rails, and special trackwork. The RF Pad/Plate system has been in service at NYCT for more than 12 years, with more than 1 million units installed.

Delkor Rubber Bonded Rail Fasteners are in use on Transit systems around the world, with many millions in service. The Delkor Fastener for Heavy Haul applications is in use on some of Australia’s highest tonnage freight lines.
