Unbranded PP-CBE20 Circular Box
The Unbranded 20mm Circular Box provides a secure termination point for electrical conduit runs in commercial and industrial environments. This specific fitting allows for a single entry point, facilitating the end-of-line connection for 20mm piping systems. It maintains structural integrity under mechanical stress during installation. The unit integrates into surface-mounted or embedded electrical networks. It ensures cable protection at every terminal junction. Engineers utilize this component to house wiring connections safely within a non-conductive enclosure.
Key Features
-
High-Impact uPVC Construction
The chassis utilizes heavy-duty unplasticized polyvinyl chloride to resist mechanical deformation and impact damage during onsite handling. -
Precision Threaded Inserts
Integrated M4 brass pillars provide reliable fastening points for conduit box lids or various light fitting accessories. -
Standardized Dimensions
- Standard 50.8mm fixing centers accommodate most universal conduit accessories and mounting plates.
- The 20mm entry diameter matches standard rigid or flexible conduit specifications for tight friction fits.
-
Environmental Resistance
The material composition offers inherent resistance to acids, alkalis, and inorganic chemicals commonly found in construction environments. -
Thermal Stability
The component operates efficiently across standard temperature ranges without losing its dimensional accuracy or structural rigidity.

Why Choose PP-CBE20
-
The terminal housing simplifies cable management by providing a dedicated end-point for circuit wiring termination.
-
Additionally, the non-conductive properties of the uPVC material enhance overall system safety by preventing electrical leakage.
-
Contractors find the material durable enough to withstand the pressures of concrete casting in embedded installations.
-
Standardized M4 threads ensure compatibility with a wide range of cover plates and ceiling roses from different manufacturers.
-
Bulk packaging in 150-piece cartons streamlines procurement for large-scale infrastructure and residential development projects.
-
The smooth internal bore prevents snagging during cable pulling operations through the 20mm entry port.
-
However, installers must ensure proper adhesive use with solvent cement to achieve a moisture-resistant seal at the joints.

Perfect for ending the conduit run. Clean white finish that blends well with the office walls. No complaints so far.
Evans Kiprop (verified owner) –
It does the work, though the lid screws were a bit stiff on a few units. Once fixed, it’s solid. Good for basic terminal points.
Samuel Njuguna (verified owner) –
Fair price and the material is sturdy. Using them for my workshop extension and they are holding up well against the heat.
Kevin Omolo (verified owner) –
We ordered a bulk of these for a residential project in Kitengela. Even though they are unbranded, the threading is clean and the 20mm entry is precise. It saved us a good amount on the budget compared to the expensive brands without compromising on the final finish of the surface wiring.

Standard 1-way box. The plastic is thick enough and doesn’t crack easily when the fundis are fixing it. Delivery here in Westlands was very fast.
