Universal Connector Mounting Bars
Bourns® Universal Adapter Bars accommodate the compact spacing dimensions of the C(G)-391, C(G)-390, C-388 and C-377
connectors. They are normally used by mounting them on the ends of the transverse arms of the distributing frame at 8 inch centers.
They may also be mounted on existing verticals using the slots provided. All the bars are made of 3.4 mm (0.135 in.) thick x 38 mm
(1.5 in.) wide plated steel. The mounting bar provides electrical conduction when the distributing frame is used to provide a ground
path for the connectors.
