Gravity WB123B Round Cast Iron Base for M20 Poles

The Gravity WB123B is a round cast iron base designed to anchor M20–threaded microphone poles and stands with exceptional mass and stability. Cast iron construction provides the low centre of gravity required for heavier microphones, boom arms, or tall configurations that would otherwise become top–heavy. The circular footprint measures wide enough to prevent tipping while remaining compact for stage or studio use where floor space is limited.

The base accepts standard M20 threaded poles, the diameter most commonly found on professional microphone stands, speaker poles, and related support hardware. Cast iron delivers substantially more weight per unit volume than pressed steel alternatives, keeping stands planted during adjustment or accidental contact. The round profile eliminates protruding corners that cause trip hazards or interfere with cable runs, and the finished surface resists corrosion in humid environments or outdoor applications.
