Dial Blocker
A Print & Play 3D Works design
Stay Locked. Stay Loud.
The Dial Blocker is a precision 3D-printed guard designed to help prevent accidental radio adjustments during shift work, high-movement tasks, or emergency response.
Built specifically for the Motorola XPR 7550, this unit preserves full access to your controls while adding a low-profile wall around your knobs — stopping unintentional channel or volume changes when brushing against gear, jackets, or seats.
Whether you’re in healthcare security, fire service, or EMS, the Dial Blocker gives your radio the reliability it needs to perform under pressure.
Because one missed call could be the one that matters.
Key Features:
🔒 Prevents Accidental Dial Movement – Keeps your channel and volume settings locked in until you want to adjust them
🔧 Still Fully Adjustable – Dials remain easy to adjust when needed
📻 Form-Fitting for XPR 7550 – Designed specifically for this Motorola radio model
🏥 Used by Healthcare Security and First Responders
