Welcome to the Bunnings Workshop community @LeeStan00. It's amazing that you've joined us, and many thanks for your question.


I am not aware of an actual joiner piece for zinc guttering. Instead, the sections of gutter overlap by 100mm and lock into each other. Ensure that the piece of guttering you place on top is on the uphill side of your fall along the length. That way, the little ridge formed doesn't trap water as it flows along the gutter. If you remove a small section of the curled lip on the internal piece, it can make overlapping the sections easier. Once the sections are ready to be joined, you apply Selleys 310g Roof, And Gutter Silicone over the meeting surfaces, then drill and pop-rivet them together. Additional sealant is then applied over all join edges and pop rivets.


What you have there is an external bracket, and they are used to hold the gutter to the fascia. You'll place one of these directly over the joined section for additional support.


Please let me know if you need further assistance or have questions.
