Core Inserted Positioners
You can take the guesswork out of rebar placement by using core inserted positioners, which are designed to fit 1.5 inches deep, cross the core diagonally and fit tightly in the corners of the core. The core positioners perfectly position the bars in the code compliance zone and allow no movement during installation. They also have an extended tail section (safety bend), so if installed out of plane, the tail will extend outside the wall, alerting the mason to turn it in the opposite position. Double vertical core positioners also are available.
