The Scaffoldmate is designed to fit on most 4-foot fold up scaffolding along with the E-Z Box, which is a spacious box that will hold up to 25 pounds. It is easy to install without the need for tools. The product has aluminum-telescoping poles that will adjust up to 40 inches. It hooks right on the side of the scaffolding and is made of lightweight plastic that will never rust. The box will fit onto the telescoping poles but also fits on the poles of the scaffolding itself. The product allows a walk space that is free of clutter, tools are always within arms reach and eliminates back strain from going up and down a scaffold to retrieve tools.
