Warning!See page 6 for reduction factors for use with lightweight concrete.Proper Placement of “Edge” T-3 or T-3-A InsertsWhen using EDGE inserts a 1/2” thick wood washer or cut washers must be used against the ends of the loopswhen bolting the insert in place prior to placing concrete. This is necessary so that when the lifting plate is drawn downtightly it will bear against the concrete and not against the loop ends. This procedure is necessary to develop the loadsshown in the table.

Coil InsertsTotal System and Safe Working LoadsThe user must be aware of the capacity of the total lifting system since the determination of the safe working load involvesconcrete strength and safe working loads of the insert, bolt and lifting hardware. All must be evaluated with the lowestsafe load component determining the safe working load of the system. This handbook has such values listed in tabular formfor all components including the minimum concrete compressive strengths that must exist at time of use. Therefore, do notassume that an insert’s safe working load is that of the system, since the SWL’s of the bolt or lifting hardware may be lessthan that of the insert. Examine the values of all components.CoilsCoil DimensionsBoltDiameterABWireDiameterThreadsPer Inch1/2” 1-1/8” 25/32” .162” 63/4” 1-9/16” 1-3/32” .218” 4-1/21” 2” 1-7/16” .281” 3-1/21-1/4” 2” 1-11/16” .281” 3-1/21-1/4” 3-3/16” 1-11/16” .281” 3-1/21-1/2” 2-5/16” 1-15/16” .281” 3-1/21-1/2” 3-7/16” 1-15/16” .281” 3-1/2BABolt Diameter• Standard length coils are available for 3/4”, 1”, 1-1/4”and 1-1/2” diameter bolts.• Longer length coils for 1-1/4“ or 1-1/2” diameter boltsare used in T-1, T-24 Single Pick-up Inserts.Lifting SystemsCoil InsertsWarning!

Always check to make certain that youhave the proper clearance void to prevent theLifting Bolt from bottoming out.
