    performance in cracked concrete (e.g. tension zones, earthquake-resistant structures)
  • Undercut segments provide cast-in-place performance and keying load transfer with
    limited expansion forces for reduced edge distances and anchor spacings
  • Through-set style (HDA-T) provides exceptional high shear loading capacity
  • Fully removable
