The USP FT/WG form tie and wedge system allows concrete wall forms to be made from
2x nominal form lumber by accurately securing them in place while the concrete is poured.
This product is intended for a maximum wall height of 4 feet.
FT – Connect 1x and 2x nominal form lumber in low foundation walls up to 4 feet high.
WG – V-shaped wedge assures rigidity and consistent form spacing.
Materials: FT – 18 gauge, WG – 14 gauge
Finish: G90 galvanizing
Codes: See page 11 for Code Reference Key Chart
Installation:
• Use the Spacing Guide chart to determine spacing between FT units. Each level in
chart assumes 12" form boards. Wall thickness from 6" to 12".
• Install with “V” facing up.
• Use (2) WG wedges for each tie. Insert wedge into inside slots for 1x nominal
forms and outside slots for 2x nominal forms.
• No walers or stiff-backs are used.
• Vertical ties to keep forms from separating are not included.
• Form deection may be substantial. Check deection, if it is critical, and move
ties to compensate.
• Forming lumber is assumed to have fb of 1,000 psi.
• Not recommended for pours greater than 4 feet in height.
