Dahua PFA-137 Metal Weatherproof Junction Box White

Where the cable run, conduit connection, or connector assembly at the camera mounting point is too large to fit within the PFA-139, the PFA-137 is the appropriate specification. The larger internal cavity accommodates more cable volume, a larger conduit entry, or a more substantial termination assembly, without the constraints of the smaller junction box.

In white, the PFA-137 suits the same range of building surfaces as the PFA-139-W: white rendered walls, painted masonry, UPVC cladding, and light-coloured building facades across residential and commercial properties. The white finish maintains visual consistency between the junction box and the camera body, producing a tidy and professional appearance at the camera mounting point.

Metal construction provides the mechanical strength appropriate for larger junction boxes that may present a larger surface to wind loading at height and to incidental contact at accessible positions. The weatherproof cable entry ensures the installation remains watertight over its service life.

For Dahua CCTV installers across London and the UK who need the larger PFA-137 format on standard white or light-coloured building exteriors, the PFA-137-W provides the correct combination of size, colour, and material specification for a professional outdoor camera installation.
