A wall plate system with screwless cover includes a baseplate having one or more central apertures, and a shape that is complementary to the front end of an electrical box. The system includes at least one modular insert that is positionable within the central apertures of the baseplate. Each modular insert including a raised front surface and at least one access opening for engaging an operable portion of a wired device that is located within the electrical box. The system also includes a front cover having one or more cover apertures that compressively engage the raised front surface of each modular insert.

Wall plate system with screwless cover

A closure with improved cable strain relief, having a body with a closed end and an open end, a tubular base having first and second ends with the open end of the body releasably secured to the first end of the base, and a strain relief member attached to the second end of the base. The strain relief member is composed entirely of non-metallic components, and includes a plate having cutouts therein forming cable ports, each of the cutouts having a wall and an inner surface along the wall, there being a plurality of gripping teeth along each inner surface, and each wall having at least one channel therein with entry and exit slots. A cable tie securing a cable in one of the cutouts is threaded through the channel, extending out the entry and exit slots. The plate advantageously has a plurality of outer surfaces shaped to fit snugly with an inner surface of the second end of the base, and flanges located at each outer surface for attachment to an edge of the second end of the base. A mounting fixture may be attached to the plate, adapted to receive an optical fiber storage tray or other support member such as a terminal block. The plate, wall, mounting fixture and flanges may be integrally formed of an injection-moldable, thermoplastic polymer.

Closure with cable strain relief

A strain relief member is provided for use with a closure member, which strain relief is formed with a web having tabs formed therein, each with a fastener receiving slot and each formed to be bent angularly from the plane of the web to aid in nesting the cables to reduce the space necessary for the joining the cables electrically and providing strain relief.

Strain relief device and closure

A filter support base for use with an upflow forced air furnace is disclosed. A rectangular base defining a return air plenum is adapted for floor mounting support of the furnace and includes a pass-through opening in communication with the intake opening of the furnace plenum. A filter base provides a rectangular enclosure that is secured intervening between the base and the supported furnace. Within the filter box there are elongated channel members extending about the internal perimeter in planar alignment with a filter access opening for support of a received filter element in the return air stream. A cover, hinge supported above the opening, is displaceable for covering the opening during normal furnace operation and for exposing the opening when filter access is desired.
