The D12 - Rod Clamps are cast malleable iron clamps used with smooth or deformed 1/4" and 3/8" rod to tie forms. The rod is clamped securely by a bolt or nut/bolt combination. Nail holes are provided to affix the clamp to the wales. For an additional safety measure, Dayton Superior recommends bending the rod approximately 90 degrees behind the clamp (see application sketch).
