Please see the chart for standard level spacings available with the standard 5", 8", 11" or 14" legsets. Standard Levels are 0.75" thick; Ultra Levels are 1.875" thick; Rollerblock Modules are 1.75" thick. The combination of these characteristics, combined with different legset lengths, will determine ultimate spacing.
Custom legsets are available to provide nearly any spacing required for special requirements.
