Straight Coil Loop Insert
Although simple in design and fabrication, the 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 bolts, or with loops having longer lengths and of heavier wire can be
furnished, if required, on special order.
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. Note: Masons Supply does not recommend 1/2" diameter bolts for lifting/handling of precast concrete.
