Available in multiple colors to match or complement your preexisting décor and wallplates.

Keystone module housing is constructed from high-impact thermoplastic which meets the UL 94V-0 fire retardant rating.

Unloaded multimedia patch panels allow the user to build a unique cross-connection solution tailored to their specific requirements, whether it's Cat 5e, BNC, F-Type or a combination.

Each panel features individually numbered ports for quick and easy jack identification.

Standard and high-density patch panels are constructed from durable die-cast steel, and finished in a high-impact black epoxy-powder paint to provide long-lasting quality with excellent corrosion- and scratch-resistance.
