A fastening apparatus includes an inner casing including slots, an outer casing surrounding the inner casing, a shaft inserted into the inner casing, and fixed rolls between the outer casing and the shaft, wherein the fixed rolls are inserted into the slots, respectively, and a diameter of each of the fixed rolls is greater than a depth of each of the slots.

A flashing system for use with an electrical service panel is described. The flashing system includes a flashing assembly extending about a perimeter of the electrical services panel. The flashing assembly includes a support base including a planar outer surface and a flanged connection assembly extending obliquely from the planar outer surface of the support base and defining an opening configured to receive the electrical service panel therethrough. The flanged connection assembly includes an inner surface that is coupled to an outer surface of the electrical service panel for supporting the flashing assembly from the electrical service panel.

A breather drain includes a main body member having first, second and third portions. The first portion includes a threaded outer surface and a hollow inner cavity with first and second open opposite ends and at least one of the first and second open opposite ends extending from the hollow inner cavity to the threaded outer surface. The second portion includes a flange and having a central passageway therein. The second portion connects with the hollow inner cavity. The third portion includes a protrusion having first and second sides and extending from the second portion. The third portion also includes a transverse hole extending from the first side to the second side and connects with the central passageway.

A power and control assembly is disclosed. An LED driver is sized and adapted to fit within a single compartment of an electrical gang box, such as a two-gang box. An alternating current (AC) dimmer or other component is installed in an adjacent compartment. The AC dimmer supplies its output to the LED driver, which converts the AC power to an appropriate direct current (DC) power for LED lighting fixtures. The LED driver is typically recessed into the compartment, and is covered by a switch or another control element. In some cases, the switch may be a mechanical dummy selected for its aesthetic or fascial characteristics. In other cases, the switch or control element may be functional. With similar multiple-gang boxes, a number of drivers may be installed in the gang box and switches may allow both dimming and zone control.

A series module assembly particularly for drive technology includes a bus system and series modules arranged in side by side in a row on a mounting base. The series modules each have an electronics housing in which at least one electronic element is arranged. The bus system includes busbars that extend outside of the electronics housing, wherein at least one of the busbars can be electrically connected to the electronic element of one of the series modules via a plug assembly. The series module assembly is designed for wall mounting. The bus bars are pre-assembled with a mounting and bus rail and anchored to the wall. The mounting and bus rail is configured so that the series modules can be mounted on the mounting and bus rail in a direction parallel to the wall in order to establish contact with the busbars. The mounting and bus rail can be adjustably mounted at a selected distance from the wall.

An apparatus for sealing an enclosure having a front and a back and an opening on the front. A door with an inner face and an outer face, and the door is rotatably mounted to the front of the enclosure and configured to cover the opening when the door is closed. A first rim surrounds a periphery of the opening and has a first outer edge. A first gasket is attached to the first rim and configured to form a watertight seal between the front of the enclosure and the door when the door is closed. A second rim on the door is sized to surround the periphery of the opening when the door is closed. A second gasket is attached the second rim and configured to form a watertight seal between the front of the enclosure and the door when the door is closed.

Provided is a technology pertaining to a panel attachment fixture wherein a single or a pair of electrical components can be efficiently arranged on an attachment-receiving panel by use of a common fixture body, said panel attachment fixture has predetermined electric components such as switches disposed on the front surface of a flange section thereof and can be attached to the attachment-receiving panel in a state in which a body section protruding rearward from the back surface of the flange section is inserted in an attachment opening of the attachment-receiving panel. The body section has on the periphery thereof: a first member fitting part to which a single first attachment member serving as an attachment member is fitted in an independent-attachment state for independently attaching a single fixture body to the attachment-receiving panel; and a second member fitting part to which a single second attachment member serving as an attachment member is fitted in a parallel-attachment state for attaching one pair of fixture bodies to the attachment-receiving panel, with the fixture bodies being arranged parallel to each other along a first direction in an in-plane direction of the attachment-receiving panel.
