  • the metal piece is relatively malleable, plastic deformation will occur at the bight portion to relieve the encountered stresses and prevent shearing on an otherwise weakened area.
  • the present invention is utilized to grip, clasp and slice a wide range of strand diameters, the degree of resilient deformations of the flanges and uprights being a direct result of the particular diameter of strand forcibly inserted in the notches of the invention. Thus the deformations will vary to accept strands of different diameters.

  • Deflection or buckling of the uprights out of the plane of the planar plate would result in slightly offset gripping of the opposite sides of the strand material.
