When fitting a consumer unit, every detail counts — from secure connections to the final presentation. That’s why our PVC trunking (50x50mm), made from high-quality Dietzel Univolt maxi trunking, is precision-cut to match the exact width of the FuseBox F3021MZ and F3022M boards.
This is more than just a piece of trunking — it’s an installation upgrade that saves you time, keeps the job looking sharp, and makes your work stand out to clients.
Purpose-Built for a Professional Top-Entry Install
Our kit is engineered for top-entry cable routing, aligning flush with the top of the FuseBox F3021MZ (21-way) and F3022M (22-way) models.
Kit details:
- Material: Dietzel Univolt PVC maxi trunking
- Size: 50mm x 50mm
- Cut Length: Approx. 498mm
- Position: Top-entry
- Included:
- 1x Pre-cut trunking section
- 2x White push-fit end caps
- Cutting Tolerance: Prepared in-house — slight variations in length or edge finish may occur.
With the measurement matched to the board, you get a clean alignment that’s hard to achieve with standard, site-cut trunking.
Why This Is Better Than Standard Off-the-Reel Trunking
Choosing a consumer unit trunking solution tailored to your board has clear benefits:
- Perfect Fit Every Time – No measuring or guesswork.
- Professional Presentation – Neat alignment from end to end.
- Less Site Work – No need to cut to length on the job.
