Spacers
Within a scheme it is often desirable to make all columns the same height. To achieve this spacer rings are available so column height remains constant regardless of the number or size of fingers chosen. Spacer rings are often used on schemes where it may be necessary to add finger arms at a later date. We recommended that you always use a minimum of two rings per column. These can be placed at the top and base of fingers. If this is done throughout a scheme then in years to come modifications can be made quickly and easily.
