Product Information

Full details

The Brett Martin 112mm Half Round 135-Degree Gutter Angle (BR049B) is designed for homeowners and contractors working with domestic rainwater systems who need to navigate non-standard building corners. This fitting provides a reliable, watertight seal for 135-degree angles, such as those found on bay windows, ensuring efficient water management. While it is engineered for straightforward installation, it is specifically compatible with the Brett Martin Roundstyle system, meaning it may not fit profiles from other manufacturers without additional adapters.

Extended Product Information

FAQs

Is this angle compatible with 112mm half round systems from other brands?

No, it is specifically designed for the Brett Martin Roundstyle system and may not provide a watertight seal with other brands.

Can I use this for internal 135-degree corners?

This specific part is designed for external corners. Using it on an internal corner will result in incorrect alignment and leakage.

What tools do I need for installation?

A hacksaw for cutting the gutter length, a drill/driver for the fixing wings, and potentially a file to deburr any cut edges.

Do I need to apply silicone or solvent weld?

The product features integrated clips and seals designed to be watertight without additional adhesives; however, some installers prefer a small amount of gutter lubricant for easier insertion.

What is the expected lifespan of this component?

When installed correctly to manufacturer specifications, the component is highly durable and resistant to environmental weathering.

Troubleshooting

Gutter is leaking at the joint

Check that the gutter end is inserted fully into the angle and that the internal rubber seal is not pinched or damaged.

Fitting feels loose

Ensure the external fixing wings are firmly secured to the fascia and the gutter profile is pushed deep enough to engage the internal clips.

Pros and Cons

Pros

  • Easy installation due to integrated clips
  • Power-tool friendly external fixing wings
  • Compliant with major quality standards (BS EN 607/EN 1462)
  • Durable construction for long-term outdoor use

Cons

  • Limited compatibility with non-Brett Martin systems
  • Requires specific 112mm gutter diameter profile
  • Color is restricted to black

Setup, Compatibility & Care

Installation

  1. Ensure the existing gutter ends are cut squarely to allow for a clean fit into the angle.
  2. Align the gutter profile with the angle's internal seal.
  3. Utilize the integrated flexible clips to snap the gutter into place.
  4. Use the external fixing wings to screw the unit into the fascia board using appropriate corrosion-resistant fixings.

Compatibility

This product is part of the Brett Martin 112mm Roundstyle system. It is not designed to be cross-compatible with square guttering profiles or different size diameters (such as 100mm or 125mm).

Maintenance

  • Inspect the angle annually for debris buildup, specifically after autumn months.
  • Flush with water to ensure there are no blockages at the junction.
  • Verify that fixings remain tight and the seals have not shifted due to extreme temperature expansion.
