W1 Wedge

The W1 is a required component of the Simpson Strong-TieĀ® WT wedge form tie that is sold separately. The wedge tie (WT), a form tie that secures concrete forms in place while the concrete is poured, requires a wedge on each end to hold the form boards in place. These wedges are designed for easy installation into and removal from the provided slots.

  • Two W1 wedges are required for each WT tie
  • Not recommended for wall pours greater than 4' high
