B-16 Straight Coil Loop Insert, Although simple in design and fabrication, the B-16 Straight
Coil Loop Insert is highly efficient for lifting and handling precast concrete elements. Standard inserts are shown in the
chart.Special inserts for use with larger diameter coil blots, or with loops having longer lengths and of heavier wire can
be furnished, if required, on special order.
