An electron block frame pouring fixture, and a method of using the fixture, the fixture including a base member having a recessed portion surrounded on each side, the recessed portion configured to receive an electron block frame therein, and a plurality of clamp members connected to the base member proximate each of the respective sides of the recessed portion, the clamp members being configured to be selectively actuated to press a received electron block frame downward into the recessed portion, wherein the recessed portion is configured to prevent lateral movement of the received electron block frame.

Mounting clamps for coupling an accessory to a structure are disclosed. The mounting clamp includes a body configured to engage the accessory and to receive a portion of the structure, a jaw and an actuator. The jaw has a first member pivotally to the body by a first pivot that is selectively moveable, and a second member pivotally connected to the first member by a second pivot. When the first pivot is in a first position, the mounting clamp is in a first configuration adapted for clamping to a first portion of a first structure. When the first pivot is in a second position, the mounting clamp is in a second configuration adapted for clamping to a second portion of a second structure. The jaw, which is selectively adjustable between open and closed positions, is configured to clamp one of the first and second portions when in the closed position.

Embodiments of the current invention relate to a pliers wrench. Optionally, the jaws of the pair of pliers lock to an adjustable gap size and/or the gap between the jaws is aligned with a rotational axis of the pair of pliers. For example, there may be two jaws that adjust symmetrically around the rotational axis. In some embodiments, each jaw is closed toward an opposing jaw by a lever. Optionally, a locking mechanism locks the jaw when it reaches half the gap width from the rotational axis. Optionally, each jaw is closable independently of the other jaw. Optionally, a notch in the jaws forms an angle for clasping a bolt perpendicular to an axis of the device. For example, the notch may have a 120 angle.
