PVC Round Box 1-Way to 4-Way 25mm
The PVC Round Box 1W/2W/3W/4W 25MM is a round PVC box designed for 25mm conduit installations. It belongs to the PVC Components group in the Conduit and Trunking category. The product is offered in four versions: one way, two way, three way and four way. Each version is intended to suit a different number of conduit connections at a single point, so the right choice depends on the layout of your installation.
Product overview
Round PVC boxes act as junction and access points in conduit systems. Instead of running long, unbroken lengths of conduit, an installer can use a box to connect runs, change direction or branch a circuit. This makes it easier to route cables through a building and to reach them later for inspection, maintenance or changes.
The PVC Round Box is made from PVC, the same family of material used for many conduit and trunking products. Using matching materials and sizes across a run helps the system go together neatly. The 25mm size is the key dimension to confirm when ordering, as it must match the conduit and fittings it connects to.

Choosing the right way count
The number of ways describes how many conduit connections the box is designed to take. A one-way box suits a simple run that ends or passes through a point. Two-way and three-way boxes suit routes where a second or third conduit joins the same junction. A four-way box gives the most connection options at one point. Choosing a version with a spare way can be useful if the layout may change later, but the final choice should follow the plan for the installation.
Typical uses
PVC round boxes are used in a wide range of conduit installations, including:
- Building services wiring where cables must be enclosed and protected
- Junctions where conduit runs meet, branch or change direction
- Access points that allow cables to be pulled or inspected
- Tidy, organised routing around ceilings, walls and service voids
Installation notes
Before fitting, check that the 25mm size matches the conduit, couplers and bends in the run. Plan the position of the box so it remains accessible after the installation is finished. Fix the box securely and make sure the conduit enters the correct ways. Follow the requirements of the relevant wiring regulations and the instructions of the installer or project specification for the site.
Ordering tips
Count the number of conduit connections needed at the junction point and select the matching way version. Confirm the 25mm size against the existing components. If the project specification names a particular standard or accessory, check the product details against that requirement before ordering, as this listing only describes the general features shown in the product information.
