The TKM cable management units are fully applicable for retrofitting and mounting to already existing patch panels.
The units can be mounted directly in front of the existing patch panels via using the screws of the 19 inch frame of the rack.
TKM subrack mounting adapters for keystone modules are made for the usage in subracks. Because of the Eurocard format it is made for the use in standardized subracks.
