The E-ZBar is the world's first repositionable rebar spreader. The E-ZBar snaps into place to position your wall steel within your forms and can be easily removed and repositioned if a conflict arises. Our most recent design incorporates two tabs to prevent the two matts from racking. Each E-ZBar eliminates two wall chairs, one fabricated rebar spreader, and 99% of installation labor associated with these three items. The E-ZBar costs less than two chairs and a fabricated spreader and average time savings per installation is about four minutes. Our spreaders are made job specific for your wall thickness, concrete coverage, and rebar size.
