Learn how to mount your phone on a motorcycle using the Quad Lock 1" Ball Adaptor. Follow these steps for a secure, vibration-resistant setup.
Quick answer
Install the Quad Lock 1" Ball Adaptor by attaching it to your existing RAM socket arm, then mounting your Quad Lock phone case. No lanyards or straps needed.
Why the 1" Ball Adaptor works for motorcycle mounts
The Quad Lock 1" Ball Adaptor lets you use your existing RAM mount setup. It fits standard 1" ball sockets, so you don't need to replace your handlebar clamp or arm.
The patented dual-stage lock secures your phone without magnets or straps, even on rough terrain. This design reduces vibration transfer compared to clamp-style mounts.
Installation steps
- Attach the ball adaptor to your RAM arm: Insert the 1" rubber ball into your RAM socket arm. Tighten the arm's knob until the ball is snug but still allows angle adjustment. Common mistake: over-tightening can crack the rubber ball. Stop when the arm holds the ball firmly without slipping.
- Mount the Quad Lock base to the ball adaptor: Align the Quad Lock base with the ball adaptor's flat surface. Press and twist clockwise until you hear a click. The dual-stage lock is now engaged. If the base wobbles, the ball adaptor may not be fully seated. Re-tighten the RAM arm and try again.
- Secure your phone to the mount: Place your Quad Lock phone case onto the mount. Twist the case clockwise until it locks into place. Give it a gentle tug to confirm it's secure. Check that the case is fully rotated to the locked position. A half-twist can cause the phone to detach over bumps.
- Test the setup before riding: With the phone mounted, simulate a few handlebar turns and vibrations. Ensure the phone stays locked and the ball adaptor doesn't shift. If the mount rotates during the test, tighten the RAM arm further. The ball adaptor should not move independently.
