Extron carries professional BNC Strain Reliefs for Extron's MHR - Mini High Resolution cables. The rough handling that cables are subjected to in a typical AV environment can cause significant damage, resulting in poor or inconsistent video performance. The point at which the cable terminates to the connector is most vulnerable. With BNC strain reliefs lessening the pressure, cables are less likely to be damaged. BNC strain reliefs also have a sleek design, adding a finished look to the cables.
