Product Description

The safe working load of the Double Flared Coil Loop Insert is greatly increased
over that of a Single Flared Coil Loop. This increase in capacity is achieved by
welding a second loop to the same coil. By adding the additional loop, it doubles
the cross-sectional area of steel embedded in the concrete and at the same time,
increases the area of the shear cone.
The design of the  insert leaves an open space between the two loops, allowing
the  insert to "straddle" reinforcing steel or prestressing strands.
Standard sizes are shown in the chart and other sizes are
available on special order.
Minimum spacing between inserts is twice the minimum corner
distance.
