Fir tree mounts with cable ties provide a secure grip in mounting holes and protect against dirt and other impurities.

    • Friction tab inside the fir tree allows the tie to sit in mount without falling out prior to installation.
    • Fir tree provides low insertion effort yet demonstrates high extraction resistance.
    • Disc feature prevents rattling in high-vibration applications and protects against debris ingress.
