The “Comparator” data shows which of the items in the dbItem (material) database are equivalent. For example, Raco, Steel City, and many other manufacturers produce essentially the same four-square box. The Comparator data shows that these items from different manufacturers are equivalent. Currently, there are about 100,000 items from Trade Service that are cross referenced in the Comparator data.
Apex makes use of the Comparator data when creating a Comparative Analysis report, so that it can compare items between vendors that carry different manufacturers products. The data is very useful to electrical contractors. Currently, there is no Comparator data available for plumbing or HVAC contractors.
The Comparator database comes from Trade Service so please contact the company directly at 800-854-1527 (then press #2 for sales) if you wish to purchase the Comparator DB service.
