SuperTie™ Patented Smooth Rod and Gripper Series

SuperTie™ patented fiberglass form-tie systems are used to secure concrete formwork during concrete placement and initial hydration, without the inherent limitations of previously popular steel form-tie systems. SuperTie™ systems eliminate the possibility of rust stains, as well as the structural deterioration often caused by failure of patching for steel form-tie holes.

SuperTie™ 6K (.308” Rod) GND6000

SuperTie™ 6K Patented Gripper System offers an ultimate tensile strength of 6,000 pounds (3,000 pounds safe working load at 2:1 safety factor) and is most commonly used with job-built (plywood and 2×4) forms and handset modular forms. The fiberglass rod diameter is only .308 inches, making the system compatible with most commercial forming systems.

US Patent #7,819,388

SuperTie™ Bearing Plate BP615

The Bearing Plate is a required component with the SuperTie Gripper. BP615 is a 4”x4” steel plate that fits the 6K and 15K systems. G50K comes with customized bearing plate (call for details).

Non-Corrosive Fiberglass Smooth Rod (.308”)

RJD Fiberglass Smooth Rod utilizes a specially blended and formulated custom-engineered resin, made in the USA, combining ultimate tensile strength and maximizing the RJD Gripper strength. (Do not use any non-RJD engineered rod with RJD grippers; this could result in form failure and/or injury.) RJD Fiberglass Smooth Rod will never rust, eliminating the need for breakback, plugging, and patching and allowing for superior architectural finishes. RJD Fiberglass Smooth Rod 6K System (.308”) is offered in grey, tan, white, black, and brown.
