This is a set of 20 L-shaped angles. The dimensions are approximately 73mm for the short side, 128mm for the long side, and 20mm wide. The hole diameter for fixing is 5mm. The thickness is 3mm, so it's quite strong. The hole spacing is 40mm for one location, and 35mm for the rest. The material is stainless steel. I think it can be used for DIY projects such as fixing and reinforcing furniture, shelf supports, and cat walks. Screws are not included (M5 countersunk screws or tapping screws are suitable). Thank you.
