Thetford Service Door 3 No Lock Rain Diverter
🔍 Key Specifications
-
Model: Service Door 3 (No lock version with integrated rain diverter)
-
Rain Diverter Feature: Single-sided rain deflector lip at the top to help shed water and reduce ingress
-
Colours Available: Black and Grey options noted (Black one ≈ part 2680527; Grey SKU 2693825SP)
-
Dimensions & Seals: Double-seal for watertight performance; fits wall thickness of 23–39 mm; aperture dimensions typical to Door 3 model
-
Weight: Approx. 0.8 kg (Black version)
✅ Advantages & Considerations
-
Enhanced Weather Protection: The rain diverter lip significantly helps prevent water ingress—particularly important for portrait orientation doors, which may otherwise leak at the top
-
Simple Operation: Push-button latch (no integrated lock) – ideal when keyed locking isn't required.
-
Colour Matching: Available in black or grey—choose based on your exterior’s aesthetic.
-
Installation Note: Does not include inner panelling/infill—you need to supply a matching panel to cover the opening.
🛠️ Installation Compatibility
-
The rain diverter is factory-integrated—no need to retrofit guttering kits (like Fiamma Drip Stop).
-
Ensure your caravan wall thickness is within the specified 23–39 mm range.
-
For improved sealing, use compatible double-seals and ensure tight push-button fit.
🧭 Which Version Suits You?
| Feature | Choose This |
|---|---|
| Top-tier weather protection | Go for with rain diverter – the added lip helps reduce top-leak risk |
| Colour matching | Opt for Black (part 2680527) or Grey (part 2693825SP) |
| Keyed security | Choose a lock-holder variant (Service Door 3 with lock) instead |
| Extra durability | Consider upgrading to larger Service Door 6/7, both with rain diverter if carrying bulky items |
✅ Final Recommendation
If you want a Service Door 3 without a lock—but with enhanced water protection—this No Lock with Rain Diverter model is a smart choice. Just be sure to provide your own panel for the internal side, and pick your preferred colour (black or grey) to match your exterior.
