Frequently Asked Questions

What wall thickness and formboard type is the WT10 designed for?

The WT10 is designed specifically for 10-inch thick walls using nominal 2x formboard. It installs between the form boards and accurately spaces them for consistent results during the concrete pour.

Are any additional hardware or fasteners required to use these ties?

Yes. Two W1 wedges are required for each tie to complete the installation. The W1 wedges are sold separately and are not included with this listing.

Is the WT10 suitable for tall wall pours or heavy-duty forming applications?

The WT10 is designed for low foundation wall applications and is not recommended for wall pours greater than 4 feet high. For taller or more demanding applications, a different form tie model would be more appropriate.

What material and finish are used on the WT10, and why does it matter?

The WT10 is made from 18-gauge steel with a G90 zinc galvanized finish. The galvanized coating provides corrosion resistance, helping the ties hold up in the wet, concrete-contact environment typical of foundation forming work. The 5/8-inch wide formed "V" design adds rigidity for accurate form spacing and support throughout the pour.
