    Product Description

    The G245 Plastic Fixing Clip enables the closer to be mortared securely to the brickwork. They also allow shorter lengths of closer to be joined together, thus reducing wastage. The clips slide into the fixing channel allowing variable height adjustment to match brick courses. Eight clips are recommended per 2.5m length of cavity closer.

    The Right Angle Clips G246 provides a tight fit and form solid jointed corners which helps prevent misalignment. These clips are also used to form cavity frames.

    Fitting Requirements

    The tie should be turned and locked into the fixing channel allowing height adjustment to match coursing.

    Lengths of cavity closer can be joined using the G245, ensuring that the butt joints slope down at 45 degrees to the outer leaf.

    Cavity closers can be made into frame fromers by joining the adjacent lengths with a G246 slotted into the fixing channel.
