Patent abstract
A sleeve lock locks concrete reinforcing steel bars within rigid support structure retainers for stabilizing the reinforcing bars in place, while allowing the bars to spin freely within sleeves or holes within the retainers. The sleeve locks are stable couplings holding concrete reinforcing bars in position while allowing the bars to spin within the couplings. This reduces the need for tightening locks or fasteners at elevated heights of vertically positioned concrete reinforcing steel bars.
