The First Alert CX4A Extended Junction Box (Part Number: CX4AJBFTB) is a purpose-built mounting accessory for CX4 fixed turret, bullet, and dome security cameras, designed to deliver a cleaner install and better protection for wiring and connections. By creating a dedicated enclosure behind the camera, it helps conceal cabling, supports more secure terminations, and gives your installation a more polished, professional appearance in both residential and commercial environments.
This extended junction box is part of a broader CX4 accessory lineup built to maximize installation flexibility. Pair it with wall mounts when you need optimal positioning and camera aiming, or use it to support a cleaner, more durable setup where exposed conduit or surface wiring would normally be visible. For streamlined finishes, the CX4 ecosystem can also be configured with flush mounts and gangbox converter plates, helping you adapt to common electrical box formats and different mounting conditions without compromising the look of the job.
Together, these accessories help deliver faster installs, improved durability, and greater flexibility for mounting CX4 cameras on a wide range of surfaces. Whether you're standardizing installs across multiple sites or simply want a neat, protected wiring solution for a single camera, the CX4A Extended Junction Box is a smart upgrade that supports a tidy, reliable, and service-friendly deployment.
