Product Features

The RepairGrip system is a portable system designed to splice bars in situ. It is a simple and proven method to splice bars that did not have their end shop-prepared.

The RepairGrip sleeve is swaged onto the bar ends by an hydraulic tool powered by a separate power unit. The resulting connection guarantees a tensile strength of at least 125% of the nominal yield strength of reinforcing bars grade 500 MPa.
RepairGrip splices are butt-to-butt splices that are suitable to both tension and compression applications.


Benefits

  • For repair or retrofit works.
  • Fits any cold shear cut bar end.
  • No reduction of the cross section area of the bar.
  • All sleeves are individually marked allowing full traceability of material origin and manufacturing batch.
  • Manufactured under quality assurance ISO 9001.
