The Volt Footring is a 351mm (~13.8") diameter brushed 304 grade stainless steel footing that is compatible with table bases that use a 3" diameter column. This accessory is not compatible with 4" diameter columns, and is not compatible with square columns. This item is not compatible with our dual column stainless steel bases. 

You can place the foot ring at your preferred height on the column. The ring itself rises approximately 10.35" from where it attaches to the rim of the ring. 

The Volt Footring attaches to the table base using set screws. Simply slide the ring over the column and tighten the screws to set it in place. Note that the attachment process will leave marks or impressions in the column (not visible when the ring is installed).
