Metaltech Saferstack Steel Scaffolding narrow Arch Frame with Coupling Pins and Spring Locks is designed for tight working areas, thus it is ideal for high pedestrian traffic areas offering walk-thru convenience. Create your Metaltech scaffold towers with these walk-thru arch frames that are ideal for painting, masonry, remodeling, facade work, and more when space is an issue. Safety is the key to working at heights, hence our scaffolding is blue powder coated with a textured finish that improves grip for moving around, particularly in difficult job sites. Our Saferstack innovation also allows you to nest and interlock the frames for easier portability and to reduce the probability of slippage. This also helps you save 30% of storage space when the frames are stacked. Our Saferstack Steel Outdoor Scaffolding Arch Frame with Coupling Pins and Spring Locks meets and exceeds OSHA, ANSI, and CSA standards to help reduce the risk of worker injury.
