Deeply cut floor joists which leave only a small section of wood for support are a difficult problem to solve. The DP43 provides the solution with heavy duty steel and structual fasteners that more than make up for the lost support.
The DP43 will repair a notch up to 26" wide. Check out the DP24 for notches up to 6" wide.
