A drain gun includes a handle and a trigger. The handle includes a channel and a plurality of inlets. The inlets feed the channel. The trigger causes a staged release of a plurality of fluids from a plurality of cartridges to the channel via the inlets when the cartridges are stored in the handle and feeding the inlets.

Multi-cartridge drain guns, accessories therefor, and methods of use and manufacture thereof

A luminaire includes a housing and a light engine. The light engine is detachably secured to the housing and includes a lens and an optical tray. The lens has a top surface, a bottom surface, and a peripheral edge. The top surface of the lens define a lens cavity. The optical tray is supported by the lens within the lens cavity.

Luminaire with pre-assembled light engine and lens

There is provided an illuminated sign mounting system and methods for mounting an illuminated sign to a mounting surface.

Illuminated sign mounting structure

There is provided a sign insert that can house the inner components of a sign. The insert can be easily inserted into and removed from signs so that either of the sign housing or the sign insert with inner components can be salvaged and reused if the other becomes inoperable.

Illuminated sign insert

Oval exit sign

A light fixture for directing light emitted from a light source toward an area to be illuminated, including a reflector assembly within which the light source is positioned and a lens assembly detachably secured to a portion of the reflector assembly such that a lens of the lens assembly overlies the light source and such that substantially all of the light emitted from the light source passes through the lens assembly.

Volumetric downlight light fixture

Canopy mounting devices that cover junction boxes of various configurations and provide a pleasing, finished appearance to a resulting installation are disclosed. Certain embodiments of a canopy mounting device include a universal mounting plate integrally formed with a connector of the mounting device such that direct mounting to junction boxes of different configurations is possible. The mounting devices accommodate not only appropriate mountings of junction boxes within ceilings or walls but also inappropriate mountings, such as when junction boxes are recessed too deeply within a ceiling or wall or mounted with junction box edges extending outwardly from the ceiling or wall.

Mounting devices for exit signs and other fixtures

Industrial emergency unit luminaire

An emergency lighting fixture combining the functions of an illuminated sign such as an exit sign and an emergency lighting unit integrated into one housing onto which one or more emergency lights can be mounted at predetermined locations of the housing, the combined emergency lighting structure providing both exit location information and ambient emergency lighting in a single cooperatively operating device.

Emergency lighting unit/exit sign combination

An emergency lighting fixture combining the functions of an illuminated sign such as an exit sign and an emergency lighting unit integrated into one housing onto which one or more emergency lights can be mounted at predetermined locations of the housing, the combined emergency lighting structure providing both exit location information and ambient emergency lighting in a single cooperatively operating device. The present device replaces bulky prior combinations of discrete exit signs and emergency lighting units which have been assembled together essentially as individual devices without integration into a single housing or without substantial integration of operational features, the housing of the present device being only slightly larger than standard exit signage. The present fixture is preferably formed from light weight materials such as polycarbonate/ABS or sheet metal configured to mount in tension internal weight such as weight due to enlarged battery mass and the like as well as externally mounted emergency lights. Manufacture of the present fixture is improved by the ability to mold major portions of the fixture from suitable polymeric materials, thereby allowing formation of substantial portions of the fixture located internally of the housing integrally with the housing to substantially reduce the number of parts necessary to be assembled together in an assembly situation. Assembly, installation and maintenance of a molded fixture according to the invention is further improved by the ability to snap-fit together all structural elements of the fixture both internally and externally of the housing.

A lamp assembly adjustable between narrow beam and wide beam light distributions, the lamp assembly is particularly intended for housing lamping or the like for mounting to industrial emergency unit fixtures of differing size and conformation. At least one and preferably two of the lamp assemblies are mounted to a unit fixture in spaced relation to illuminate critical areas within an industrial or commercial space during emergency conditions, such as failure of mains power, to allow evacuation of the space. In order to illuminate the desired areas, each of the lamp assemblies can be adjusted along an internal track to allow light to be directed toward a particular location within a wide range of possible locations, thereby facilitating illumination of the most desirable area in the vicinity of the unit fixture for a particular mounting location. Additional flexibility in the delivery of illumination to a desired area is provided by adjustability between narrow and wide beams.
