Forming project using Sigma DG 700 Series ties

Fiberglass Form Ties

700 Series

The 700 Series form tie was developed for medium duty applications to span the gap between the 400 and 800 Series in strengths.
At just 5/8" in diameter, the 700 Series is a great combination of great safe working loads and extremely light weight. It provides all the advantages of our forming systems, just with more performance.
