Reduce Set-up Time and Protect Your Cables with PolyLiner™ FR by The Gund Company.
PolyLiner™ FR cable tray liners provide the protection and cable management afforded by standard cable tray liners but in a lightweight, easy-to-install, flexible form factor. Our flexible cable tray liners come in custom-sized rolls for ease of transport, can be cut to length to maximize space, and can be configured to match any cable tray configuration.
PolyLiner™ FR tray liners are converted using PolyPro® FR – a high-quality, UL94-V0 flame-retardant polypropylene material manufactured by The Gund Company. PolyPro® FR is available in standard black and white colors.

PolyLiner™ FR Benefits:

Compatibility: PolyLiner™ FR works with any wire basket or cable tray configuration. The product is in roll form and can be cut to length to match any tray layout. Tray liners come with removable perforations to keep cables from sliding or for attachment to cable trays.
