SuperTie™ 6K Patented Gripper System
Fiberglass Form Tie-System
Say goodbye to corrosion forever. Easier to use, saves time, and less expensive than traditional steel form ties. SuperTie™ patented fiberglass form tie-systems are used to secure concrete formwork during concrete placement and initial hydration, without the inherent limitations and rusting of previously popular steel form-tie systems.
- Reduced Labor Costs – No plugging, patching or sacking.
- Reusable Parts – Simply strip hardware from form, reuse over 100 times.
- Variety of Colors – We offer colors to blend with the wall. Custom colors available.
- Superior Finishes – Eliminates rust and corrosion. Strips flush to concrete.
- Reduced Inventory – One SuperTie™ fits any wall width.
- Electromagnetically Transparent – Ideal for situations where interference is undesirable.
Product Overview

Fiberglass ties will never rust, eliminating the need for break-back, plugging, and patching and allowing for superior architectural finishes. US Patent #7,819,388.
- Extends Form Life – All forms and form liners strip easily from the structure without damage from the ties saving money and time.
- Reusable Parts – Simply strip hardware from form, reuse over 100 times.
