ABSTRACT:
An improved sheet metal brake is disclosed. In the preferred embodiment, the invention basically comprises an elongated rod which attaches to an existing pivotable brake lever. With this extension attached to the brake lever, a user can move the lever extension back-and-forth to open and close the brake. Because the user can now stand in the center of the sheet metal, he can use his body weight to press against the sheet metal to further secure it. This prevents the sheet metal from slipping. As a result, the sheet metal is not bent off-line.
