N E T Open Coil Insert Open Coil Inserts are fabricated in two, four or six strut versions, as required. A standard coil is welded at one end of the strut wires and on the opposite end, an expanded pitch coil is welded. The expanded pitch coil welded to the more deeply embedded end of the insert, serves to distribute the applied loads over a larger volume of concrete. Thin Slab Coil Insert The Flared Thin Slab Coil Insert is designed for use in very thin slabs or other conditions where a longer insert cannot be used. Inserts should be set back 1/2" from the surface of the concrete, maintaining at least 3/4" of concrete below the insert. Minimum spacing between inserts is twice the minimum corner distance. SWL is based on 1/2" set back from face of concrete and sufficient coil penetration by the lifting bolt. SWL provides a factor of safety of approximately 4 to 1 in 3,000 psi normal weight concrete. Refer to the coil bolt chart onminimumcoil bolt penetration. Consult manufactures data for values on shear and reduced edge distance.
