FAQs
Can I use this with round gutters?
No, this product is specifically designed for 112mm square gutter profiles only.
What is the degree of this corner piece?
This unit is designed for a 135° angle, suitable for obtuse building corners.
Does this product require special tools to cut?
No, it can be cut using standard hand tools like a fine-toothed hacksaw.
Is the black finish paintable?
While the finish is durable, it is not recommended to paint the guttering as this may affect the thermal expansion performance.
How do I secure the angle to the gutter length?
The fitting uses a push-fit design with internal seals; ensure the gutter length is pushed home firmly into the fitting until seated.
Troubleshooting
Water leaking at the joint
Check that the gutter end is inserted fully into the fitting and the rubber seal is seated correctly.
Fitting feels loose on the fascia
Ensure additional gutter support clips are placed within 150mm of the joint to bear the weight of the water.
Pros and Cons
Pros
- Quick and straightforward installation process
- Highly durable against extreme environmental conditions
- Lightweight material reduces handling fatigue
- Seamless integration with 112mm Polypipe square systems
Cons
- Not compatible with round gutter profiles
- Available only in black, which may not match all building aesthetics
- Requires proper adhesive or sealants for permanent watertight joints
Setup, Compatibility & Care
To install, ensure your fascia boards are level and properly secured. The gutter lengths should be cut to size using a fine-toothed saw before being fitted into the 135° angle unit. Always ensure the internal rubber seals are clean and free of grit before assembly to maintain a watertight connection.
For ongoing care, keep the gutters free from leaves and debris to prevent blockages that put excess weight on the corner fittings. During the annual inspection, check that the unit remains securely clipped to the fascia brackets. Use only mild soapy water for cleaning; avoid harsh chemical solvents that could degrade the plastic finish.
