The Werner L400002 12in Cast-In-Place PVC Sleeve is designed to be cast into freshly poured concrete and comes with a cap to seal the end preventing fresh concrete from filling the sleeve. After the concrete has cured the Werner L400001 End Stanchion or the L400003 Intermediate Stanchion can be inserted into the L400002 Cast-In-Place Sleeve creating raised anchor points for the Werner horizontal lifeline.
