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.
.Above capacities are based upon mechanical testing and available industry data.
.Table is based on 3,000 psi and 145 PCF concrete. .Minimum spacing of inserts is 2 x (corner distance).
.Inserts must be set back 1/2”from concrete surface.
