Black Box Modular Adapter Kit DB9 to RJ45 (Black)

The Black Box FA4509F-BK is a modular adapter kit that converts a DB9 interface to an RJ45 jack, giving you a simple way to bridge serial equipment with structured cabling. Because it arrives unassembled, you can arrange the pinout that matches your exact hardware requirements, eliminating the need for prewired adapters that may not fit your setup.

This kit is a practical choice for network administrators, system integrators, and field technicians who need to bring legacy DB9 devices into modern racks. Once assembled, the adapter can be mounted in a blank patch panel, which keeps cables neatly organized and makes future moves, adds, or changes easier to manage.

A robust housing and precise engineering help maintain solid, long-term connectivity, even in busy server rooms or industrial control cabinets. The black finish blends well with most rack environments, creating a professional, uniform appearance across your installation.
