Metaltech Saferstack Plaster Frame Scaffolding set is specially designed scaffolding for work in tight spaces. It is ideal to use scaffolding for painting, masonry, remodeling, facade work, and more. Safety is the key to working in heights, and so our scaffolding is finished with a textured powder coated paint that improves grip. Our Saferstack innovation also allows you to nest and interlock the frames for easier portability and to reduce the probability of slippage when storing. This also helps you save 30% of storage space when stacked. Our Saferstack Plaster Frame Style Scaffolding Arch (1 Section) meets and exceeds OSHA, ANSI, and CSA standards to help you reduce the risk of worker injury. Material: Steel.
