Abstract: A frame assembly for retaining a tool for use in a press having a gripper margin that is larger than the gripper margin of the tool. The assembly includes a frame member having a lower wall including an opening, back wall and upper wall defining a rectangular channel. Also include is a rectangular spacer adapted to fit within said channel and sized to increase the effective length of the tool to match the gripper margin of the tool with the gripper margin of the press. The assembly further includes an extension on said spacer located to engage an opening in the lower wall.

Abstract: A hand tool consisting of an outer grip having an elongate inner housing formed therein engages with wing knobs used to tighten and loosen hanging file clamps. The outer grip is provided with a plurality of planar elongate gripping surfaces to enable a user to apply greater force to the wing knobs, which are frequently over-tightened by previous users. A pair of lattitudinally extending inner frame members are used to form two receiving areas for the wing knobs, a central elongate recess receives wing knobs of smaller diameter. By vertically recessing the upper surfaces of the inner frame members, wing knobs of greater diameter are received within the entire elongate inner housing.
