The Manfrotto 231B Column Stand is a black anodized aluminum,
wheeled, single column stand that is perfect for studio use. It features
a spring-loaded sliding arm that allows quick height adjustment of your
light fixture from almost floor level to nearly the top-most of its 8'
chromium steel column.
The 231 has a leveling leg, which extends and locks, making the load more stable on uneven surfaces such as steps.
