Do the different series and part numbers relate to the physical aspects of the parts?
Yes, each series number indicates a different fence height; the minimum height of an assembly using the specific series is indicated by the series number: 10 SERIES = .13″ MIN. (3.3) 20 SERIES = .20″ MIN. (5.08) 40 SERIES = .40″ MIN. (10.16) 50 SERIES = .50″ MIN. (12.7) 80 SERIES = .80″ MIN. (20.32) Taller assemblies using a specific series number can be attained by increasing the cover height; for example, a 1″ (25.4) tall assembly can be achieved using the 50-CBS series fencing by increasing the standard cover height by .50″ (12.7). Each specific series sub-number indicates a different fence configuration relating to mounting pin spacing and standoff availability.
