The O.C. White Heavy Duty Spring is intended for use with O.C. White Deluxe Microphone Arms and provide extra support when mounting heavy microphones. The spring may replace or be used in conjunction with the standard (regular duty) springs, allowing the Deluxe Microphone Arm the ability to support up to 8 lbs (3.62 kg).
Note! This is a single spring. The O.C. White Microphone Arms require a pair (2).
