Check the listing for details. Custom Button Knob Guard Attachment Protector for Hytera BD502i 2-way radio. Condition: New. Listed at 8.95 USD. Custom 3D Printed friction fit guard to help prevent accidental volume/channel changes during light everyday use. Cutouts on either side provide enough room to make small adjustments to volume and channel knobs without needing to remove the guard. It is supposed to clip onto a line in the antenna, and this helps a bit. Not secure enough for heavy duty or very active use. Choose Red or Black from the drop-down menu As far as I know, this only fits the BD502i, but may fit other models if they happen to have exactly the same dimensions.
