EFB Elektronik 53711.5 3U/7HP Module Insert for 6x LC Duplex, Unpopulated, Light Grey

For fibre installers who prefer to build their own patching setup, the EFB Elektronik 53711.5 module insert offers a blank canvas with six precision-punched LC duplex cutouts. Unlike pre-loaded panels that lock you into a specific adapter brand, this unpopulated 3U/7HP insert lets you snap in the exact LC duplex adapters your project demands—whether you standardise on one manufacturer or mix flange styles for custom density. The galvanised steel body with RAL 7035 light grey finish matches EFB rack frames seamlessly, keeping your 19-inch cabinet looking uniform even when modules are mixed.

Highlights

• 3U / 7HP form factor for EFB-Elektronik 19-inch rack frames
• Six LC duplex cutouts for snap-in fibre adapters
• Unpopulated module — add your preferred LC duplex adapters
• Galvanised steel body with light grey RAL 7035 finish
• Compatible with EFB-Elektronik 3U patch panels and rack systems
• Indoor use, designed for structured fibre infrastructure

In daily use

Because the insert is unpopulated, you are not tied to a specific adapter brand or flange style. Snap-in LC duplex adapters can be clicked into place from the front, and the module can be installed in any EFB 3U frame that accepts 7TE-width inserts. The steel construction keeps the front panel stable when repeated connecting and unplugging occurs. The compact 7HP width makes it easy to combine adjacent modules in the same 19-inch patch panel, keeping high-density fibre racks tidy and fully customisable.
