If you are using a handheld radio with a belt clip or button on the back of the device, you can conveniently mount it in your car using the Universal Handheld Radio Holder. The smaller version V-slot is designed to hold devices with a button on the backside. The larger version V-slot is designed for a larger belt clip to attach and slide through for a secure hold. Easily slide your handheld radio in and out on the trails and keep your device safely at hand during any off-road adventure.
