JB120C 20mm 1 Way Shallow Electrical Conduit Junction Boxes

Description

20mm. 1 Way. Shallow. Round. Grey PVC Conduit Junction Box.

The Rylec JB120C is a 20mm one way shallow round PVC conduit junction box — providing a compact in-line junction point on a single run of 20mm conduit. The shallow depth keeps the profile low against the mounting surface, and the round form factor allows rotation to align the conduit entry in any direction. Grey PVC construction to match standard grey conduit. Sold individually.

Where the JB120C One Way Shallow Junction Box Fits

A one way shallow conduit junction box provides a protected, accessible junction point at the end of a single conduit run — used where cables need to be terminated or transitioned from a conduit run into a wall, enclosure, or piece of equipment without a second conduit connecting out the other side. The single conduit entry means the JB120C is most commonly used as a conduit end cap with access — protecting the cable end while giving a neat, removable lid access point for the cable termination inside. The shallow depth keeps the box low against the wall or surface for a clean installation in spaces where a deeper box would be impractical.

The round shape allows the box body to be rotated on its mounting point, so the conduit entry can be oriented in any direction — up, down, or to either side — without needing different product variants for each installation direction. Grey PVC matches the standard grey conduit system used in most Australian residential and commercial electrical conduit installations.

The JB120C is part of the Rylec JB shallow junction box range, which covers 20mm and 25mm conduit in 1-way, 2-way, 2-way angled, 3-way, and 4-way configurations — allowing the right junction box to be selected for each junction point in the conduit run based on the number of conduit entries required.

Q: What is the difference between a 1-way and 2-way shallow conduit junction box?
A: The number indicates how many conduit entries the junction box has. A 1-way (JB120C) has a single conduit entry — used at the end of a conduit run. A 2-way (JB220C) has two entries — for an in-line through-connection or a direction change. A 3-way (JB320C) has three entries — for a T-junction in the conduit run. A 4-way (JB420C) has four entries — for a cross-junction.

Q: Is the JB120C suitable for 20mm rigid conduit or corrugated conduit?
A: The JB120C is sized for 20mm conduit. It is compatible with 20mm rigid PVC conduit and 20mm corrugated flexible conduit with appropriate adaptor fittings. Confirm conduit compatibility with the fitting type before installation.
