The Grommet Mount Accessory for WorkFit-S workstations can be used to install the WorkFit-S in situations where the "front mount" clamp that WorkFit-S units are equipped with will not work. This could include locations where there is insufficient space for the clamp on the underside of the desk or where unusual design of the mounting location precludes the use of the standard clamp. The Gromment Mount Accessory requires a grommet or single drilled mounting hole (0.375" to 2.5") centered 8.5" back from the edge of the mounting surface and can accommodate thicknesses from 0.47" to 2.4" thick.
