Product Overview

Engineered specifically to protect delicate smartphone optical image stabilization (OIS) camera modules from destructive engine harmonics and off-road vibrations, the SEAMETAL 8-Claw Anti-Vibration Motorcycle Phone Mount provides complete multi-directional phone retention. Featuring four decoupled high-elasticity silicone damping columns and an eight-claw mechanical surround, it absorbs road chatter and eliminates drop risks over washboard gravel, speed bumps, and high-speed highway cruising. Available in U-bolt handlebar and rearview mirror stem mounting configurations with full 360-degree rotation.

Step-by-Step Installation Guide

    • Mirror Style: Unthread the rearview mirror, slip the Y-shaped bracket hole onto the mirror stem thread, and torque the mirror back down tightly.
  2. Ball Head Connection: Insert the 360-degree ball head into the rear dampener socket, adjust your preferred viewing tilt angle, and hand-tighten the collar nut.
  3. Width Calibration: Loosen the rear adjustment screws, press both sides of the stand panel inward to match your phone's exact width, and retighten securely.
  4. Device Placement: Slide your smartphone downward into the bottom claws and push inward until all eight claws seat flush around your phone.
  5. Clearance Test: Turn the handlebar from lock to lock to confirm that the mount and phone do not interfere with the gas tank, windscreen, or instrument display.
