The Osma SquareLine Gutter Jointing Bracket (100mm) is designed for professional contractors and DIY enthusiasts installing or repairing the Osma SquareLine gutter system. Its primary benefit is providing a secure, leak-free connection between two gutter lengths while mounting directly to the fascia, significantly simplifying the installation process by removing the need for separate brackets at joints. While highly efficient for the SquareLine range, users should note that it is specifically engineered for 100mm SquareLine profiles and is not compatible with round-profile guttering systems.

No, this bracket is specifically designed for the 100mm SquareLine profile and will not provide a secure fit for round systems.
No, this component is designed to act as a joiner and a support bracket in one, eliminating the need for an additional bracket at the joint.
It is manufactured in accordance with BS EN 607:2004 for drainage components.
The seals are wide and retained within the housing. We recommend replacing the entire bracket if the seals become damaged or lose their elasticity.
It is intended for standard flat fascia mounting; if your fascia is irregular, ensure a mounting block or shim is used to create a flat, level surface.
Check that the gutter ends are pushed fully into the bracket and that the seals are not pinched or twisted during installation.
Verify that the bracket is securely fastened to the fascia and that the gutter sections are properly supported by adjacent brackets if the span is significant.
Ensure the gutter end is cut perfectly square and check for any plastic burs or debris on the edge of the cut.
For installation, ensure your fascia board is secure and level before attaching the bracket. Position the bracket at the desired join point and fix it firmly to the fascia using suitable corrosion-resistant screws. Insert the 100mm SquareLine gutter lengths until they meet the internal stop of the bracket. To ensure long-term care, clear the gutters of leaves and debris at least twice a year. During regular inspections, check that the seals remain flexible and that no gaps have formed due to house settling. The component is compatible exclusively with the Osma 100mm SquareLine range; ensure all other fittings, such as downpipe adapters and stop-ends, are also from the same 100mm SquareLine series.
