PRODUCT DETAILS
C-Line Circular Back Box – Grey: Secure & Professional Wiring Housing
The C-Line Circular Back Box (Dark Grey) is a versatile yet essential component within the C-Line (Powerpart/CBE) modular electrical system for caravans, motorhomes, and campervans. Designed as the protective rear housing for 12 V, USB, TV, and 230 V socket inserts, this back box delivers both secure mounting and tidy wire management behind your caravan panels.
🛡️ Durable Build & OEM Look
Constructed from robust ABS plastic in a sleek dark-grey finish, this back box blends seamlessly with interior faceplates and trims. Its tough design ensures reliability and longevity even on rough touring roads .
🔌 Precision Fit & Compatibility
The box is tailored to fit recessed C-Line modular inserts—like PO253 sockets and PO250/PO296 covers—providing recessed protection and neat cable routing. It’s compatible with most caravan and motorhome brands, including Bailey, Elddis, Adria, and Coachman.
🔧 Simple Installation
With easy snap-in cable-entry grommets and compact dimensions (~50 mm depth × 53 mm diameter), it fits into a 48–51 mm drilled hole cleanly . The clever tab design secures modules without needing heavy-duty tools. However, some users recommend drilling out the top tab slightly to avoid snap issues during install.
💡 Professional Wiring & Protection
This protective housing ensures wires and soldered joints are fully enclosed—meeting safety best practices and preventing shorts or debris contact. A deeper variant (~60 mm depth) is available for thicker panels or stacked modules .
✅ Final Verdict
The C-Line Circular Back Box – Grey is an affordable, modular solution for tidy, secure electrical fittings. Reliable, easy to install, and compatible with a wide range of inserts, it’s the go-to choice for both OEM and DIY projects in leisure vehicles.
