Coil InsertsExposed Aggregate DetailsExposed Aggregate Face DownFor exposed aggregate panels cast face down, theheight of the coil insert should be 3/8” less than thestructural panel thickness. If inserts are ordered foroverall panel thickness, they will be too high whenplaced on aggregate.OverallPanelThickness3/8” NormalSetbackProperlytie insertto reinforcingExposed AggregateStructuralPanelThicknessLifting SystemsCoil InsertsExposed Aggregate Face UpFor exposed aggregate panels cast face up, the heightof the coil insert should be the same as the structuralpanel thickness and not protrude up into the exposedaggregate.OverallPanelThicknessProperlytie insertto reinforcingExposed AggregateStructuralPanelThicknessLifting Exposed Aggregate Face UpWhen lifting exposed aggregate panels cast face up, ifaggregate is carefully tamped and leveled during aggregateplacing, it may not be necessary to place a groutor bearing pad under lifting plate. If aggregate surface isuneven, a plywood bearing pad is recommended underthe lifting plate.Grout orBearing PadWhen used with large exposed aggregate face up panels,a grout pad is required to provide a bearing surfacefor the plate. Longer length bolts will be required forthese panels.

Coil InsertsHow to use Coil Face Inserts1. 2. 3A.Position insert in place andwire securely to rebar. Makesure coil is perpendicular topanel face.Place concrete, vibrate carefully inregion of insert, and use screedingtechniques which will prevent crownsin slab. Excessive slab thickness willincrease setback dimensions and willrequire the use of longer bolts.3B.After plastic plug has beenlocated, chip concrete cover offand with a pair of pliers pull theplug out of the coil.Remove T-21 Plastic plug byprying it out with a screwdriverLifting SystemsCoil Inserts4. 5. 6.Hole should be small and conciseand if not used immediately shouldbe plugged to prevent debris andwater from entering.Clean hole with compressed air .then place lift plate directly overinsert hole.Slip bolt through hole in lift plateand start bolt into coil by hand.7. 8. 9.Turn bolt clockwise with a wrenchuntil bolt is secured tight againstlift plate.Attach crane line (use doubleclevises or swivels to take outtwists in crane line) to lifting bail.Apply initial tension to crane linesand make sure bail is aligned indirection of applied load.To remove lift plate after panel iserected turn bolt counter clockwisewith a wrench until bolt isfree.Danger! Crane line loads and bail of double-swivel lift plate must be turned in direction of crane forces before lifting operation begins.Crane line loads must not be allowed to apply sidewards loads to bail as this condition is dangerous and could lead to premature failureof hardware.04-0961
