Floplast 90 Degree Angle Square Line Gutter

The FloPlast 90 Degree Angle Square Line Gutter is designed to guide your guttering smoothly around the corners of a building. Creating a precise 90° turn, this fitting allows rainwater to continue flowing efficiently around both internal and external corners, helping maintain the overall performance of your gutter system. One of the key benefits of this square line angle is its symmetrical design. There’s no need to choose between internal or external versions — the same fitting works perfectly for both. This makes installation simpler, reduces ordering confusion, and ensures a consistent finish across your roofline. Available in Black and White, it offers a clean, coordinated look to suit both traditional and modern properties.

Versatile Symmetrical Design

Because the fitting is fully symmetrical, it can be used on any 90° corner, whether internal or external. This practical feature saves time during installation and ensures flexibility when planning your gutter layout. The square line profile not only provides a sharp, contemporary appearance but also delivers strong water-carrying performance, making it ideal for residential and light commercial buildings.

Proper Support for Lasting Performance

To maintain the integrity of the system, it’s important to correctly support the angle during installation. A fascia bracket should be positioned within 150mm on both sides of the fitting. This added support prevents sagging when the gutter is weighed down by heavy rain, standing water, or snow. Manufactured from durable, weather-resistant uPVC, this gutter angle is built to resist cracking, corrosion, and fading, ensuring long-term reliability with minimal maintenance.

Colour Options to Match Your Roofline

Black – A bold, versatile choice that complements most fascia and soffit styles. White – A crisp, clean finish ideal for bright, classic rooflines. Both colour options offer the same strength, durability, and dependable performance.

FAQs

Can this be used for both internal and external corners?

Yes. The symmetrical design means the same 90° angle fitting is suitable for both internal and external corners — there is no difference between them.

How should the angle be supported during installation?

A fascia bracket should be installed within 150mm on both sides of the angle. This helps prevent sagging under the weight of water or snow and keeps the gutter aligned correctly.

Is this compatible with half round gutter systems?

No, this product is specifically designed for square line gutter systems. It should be used with compatible square line gutter lengths and fittings for a secure and watertight installation.

Roof Tiles & Fittings:

We recommend ordering an additional 10% of roof tiles to allow for any breakages that may occur during delivery or handling. Roof tiles are naturally fragile, and having a few extra on site helps prevent delays and ensures your roofing project can be completed without interruption.
