Where the Rylec JB125C Junction Box is Used

Shallow conduit junction boxes are used in surface-mounted conduit installations to provide an enclosed access point for cable terminations, joints, or changes in conduit direction at the end of a conduit run. The JB125C is the 1 way version — a single conduit entry — making it the correct box for termination at the end of a conduit run where one conduit arrives and no other conduits continue from that point. The cable passes through the conduit, enters the box through the single entry point, and is terminated or joined inside the box, which is then closed and forms the end point of the conduit run.

The shallow profile reduces the box's protrusion from the mounting surface compared to a standard depth junction box — important in surface mounted conduit installations where minimising the total depth of the installation off the wall or ceiling is a priority. The round shape is the standard form for single-entry conduit termination boxes, providing a compact enclosed volume for the cable termination without excess space.

The Rylec JB range covers 1 way through to 4 way configurations in the 25mm shallow format — all grey PVC, all the same round profile — allowing the correct number of conduit entries to be selected for each junction point in the installation. Use JB125C for single-entry termination; JB225C, JB325C, or JB425C for junction points where 2, 3, or 4 conduits meet.

Q: What does "1 way" mean on the JB125C?
A: "1 way" means the box has one conduit entry point. A 1 way junction box is used at the end of a single conduit run — one conduit arrives and terminates at the box. For junction points where multiple conduits meet (branches, tees, crosses), use the 2 way (JB225C), 3 way (JB325C), or 4 way (JB425C) versions.

Q: What conduit size does the JB125C suit?
A: The JB125C suits 25mm conduit — both 25mm corrugated flexible conduit and 25mm rigid PVC conduit systems.

Q: What is the difference between a shallow junction box and a standard junction box?
A: A shallow junction box has a reduced depth profile, minimising the protrusion off the mounting surface in surface mounted conduit installations. A standard depth junction box provides more internal volume for larger cable bundles or more complex terminations. Use shallow boxes where space is limited or a lower profile installation is required.
