Abstract: Roof clamps and methods of securing roof clamps are provided. The roof clamps include a saddle, a wedge, and a securing member. The securing member facilitates engaging a seam of a roof with the clamp and removably fixing the roof clamp to the seam through the camming action of the wedge against a region of the saddle. The securing member also serves as the connection point for an auxiliary item, such as a solar panel or a snow guard. The placement of the securing member allows the roof clamp to be secured from, and the auxiliary item to be attached at, a top surface of the saddle.

Abstract: An adjustable pedal assembly includes a screw (62) for moving a pedal (16) along a rod (22) between a plurality of adjusted positions. A conduit (53) rotatably supports a core element (55) that is rotated by an electrical motor (52). A pair of female (56) and male (57) connectors attach the conduit (53) in an operative position on a gearbox (20) with the core element (55) connected to a worm (58) engaging a worm gear (60) to rotate the screw (62). Any such adjustable pedal assembly may be characterized by a pair of electrical contacts (70) and (72) supported by the respective connectors (56) and (57) for electrical contact to transmit electrical current through the electrical leads (74) and (76) when the connectors (56) and (57) are connected together but for discontinuing electrical conductivity when the connectors (56) and (57) are separated. The drive motor (52) is operative only when the connectors (56) and (57) snugly interconnected.
