  • Top rail tie bracket for concrete forms
    Patent number: 4125245
    Abstract: A top rail tie bracket for concrete forms for eliminating the usual additional wooden rail required across the top of the top rail of the form for bracing the wedging element of the top snap tie rod. A reusable T-shaped bracket is provided, one leg of which abuts the top rail and the other leg serves as a back-up support to overcome the tensioning action of the wedge on the top snap tie rod. This eliminates the necessity of the additional top rail.
