The Add-On Support, Model 46601-G, consists of a support rack that can be installed on the two-workstation Work Bench, Model 46601-2. This enables the user to place some of the bigger modules on the front and save space on the work surfaces of the bench.

The Add-On Support, Model 46601-G, is a variant of the Add-On Support, Model 46601-F, that does not protrude from the work bench and thus requires less space. It does, however, require a wiring duct.
