Note: The mute is slightly smaller than advertised so that it can be clipped on and stay in place. This means the mute will "stretch" somewhat when it is put into place. If you wish a looser fit, select a larger size. Here are the measured specs for thismodel:
• Advertised nominal size: 10.5 inches
• Actual mute body diameter (approximate): 9-5/8 inches
• Actual inside distance between the clips: 10-3/8 inches
