Help
Welcome to the Bunnings Workshop community @malh. It's wonderful to have you join us, and many thanks for your question about installing doors.
It sounds like our helpful members will need more information to assist you with this project. If you could please let us know what type of doors these are and where you'd like to install them, that would give us an idea of what you're working with. Feel free to include an image of the doors as well.
