Simpson Strong-Tie Wedge Tie Forming System

The Simpson Strong-Tie Wedge Tie (WT) is a form tie that secures concrete forms in place while the concrete is poured. It easily installs between form boards and accurately spaces the forms. Several models are available for varying wall thickness and types of form boards. The spacing of the wedge ties along the length of the form depends on the depth of the wedge tie in the form. The spacing does not depend on the thickness of the wall. The maximum recommended spacing for Simpson Strong-Tie Wedge Ties used with 1x, 2x and 1-1/4" thick forms is outlined in the Simpson Wedge Tie Technical Bulletin. The tables give spacing guidelines for various form heights and types of form boards. In general, the higher the form is, the closer the spacing of the WTs should be.
