F-42 Loop Ferrule Insert is fabricated by welding a looped strut to a closed-end ferrule.
F-42 insert is available in the sizes shown in the chart below and is well suited for structural connections and the
suspension of equipment, piping, etc.
Minimum spacing between inserts is twice the minimum corner distance.

Safe Working Load provides a factor of safety of approximately 3 to 1 in 3,000 psi normal weight concrete.
Safe Working Load are based on 1/2” setback from face of concrete.
