The Expanded Coil Ferrule Insert is a high-strength, highly versatile insert available for numerous precast concrete applications. It is available in 3/4”, 1”, 1-1/4” and 1-1/2” bolt diameters. The insert is constructed with a NC threaded ferrule, shaped struts (two, four or six depending on model) and an expanded wire coil. This efficient design increases the shear cone surface area thus increasing the load capacity of the insert.
Standard finish is plated. Plated inserts are not designed for use with hot dip galvanized bolts, due to thread engagement.
