Our rebar chucks are designed to be used for proof testing and tensile strength testing.
They are available in sizes #3 to #11 rebar.
They are re-usable with wedges averaging 30 to 40 uses depending on testing conditions.
Rebar chucks are reusable. Each jaw segments comes as one piece. You must separate the jaw segment by putting the whole jaw in a vice or using a hammer. The jaws can be broken into pieces. Only use two pieces, one on each side of the rebar between the longitudinal rib. Each jaw segment should last 50 to 60 uses (based on grade 60 rebar). More uses can be expected on softer rebar.
