Re: PICTURE HANGERS SUITABLE FOR FIBRO INTERNAL WALLS
Welcome to the Bunnings Workshop community @Jubes. It's fantastic to have you join us, and many thanks for your question about hanging pictures.
For a cement fibro internal wall, you'll either need to find a stud to use an Everhang 8kg Brass Plated Picture Hook in or use a hollow wall anchor. If there is no conveniently located stud, then spring and gravity toggles can be used. Generally, there should be enough room to mount a hollow wall anchor where a sliding cavity door is located. You might want to check first how thick the door is and how wide the cavity is. If it's a particular thin partition wall, then there is a chance that the toggles will contact the door, especially if they are coming in from both sides. Before you start drilling holes into walls, I just wanted to verify that you've had the wall tested, and it's not asbestos? I use a standard timber or metal drillbit on my fibro walls. Taping the area will assist in preventing excessive damage to the paintwork.
Alternatively, if you clean the wall well, you can use the Command™ Large Metal Adhesive Universal Picture Hanger. Their rating is 2.2kg, so they should cope well with your 1kg picture. I'd certainly recommend this option if you don't know what the wall is made of. It also could just be a simpler solution than worrying about whether the door will hit the toggles.
