| CONSTRUCTION |
| Precision formed, TIG welded, one piece 18 gauge cold rolled steel housing. One piece 60° beveled perimeter door frame, fabricated from 18 gauge, type 304 stainless steel, with TIG welded corners. The door assembly is self-centering by means of locating studs. It is retained by retractable hinge brackets when opened. Continuous retention-mounts mechanically secure and evenly distribute force against both gasketing and diffuser. Welded studs are used in order to mount components, offering superior performance over PEM style fasteners. Construction design feature reverses the tendancy for the lens door frame to bow outwards. Specialized, military grade, flat head, stainless steel, captive fasteners with integral silicone o-rings easily secure door frame to housing through use of floating cage nuts. Silicone o-rings offer superior performance and longer life over comparable teflon bushings. Protective stops prevent the fasteners from being overtightened and bending the lens door frame. Custom shaped, extruded closed cell silicone gasketing is used throughout to ensure precise, redundant seals between door assembly, housing and plenum. Vulcanized corners ensure continuity of the seal on the frame gasket. Housing has integrally formed ribs surrounding plenum access cover opening in order to ensure integrity of seal. |
|
| MOUNTING |
| Swing arm mounting brackets, with vertical adjustability, are used to mount the fixture against the ceiling. On 4' units, six brackets are used in order to provide improved continuous seal to plenum with less fixture distortion. |
| FINISH |
| Powder painted white. housing. |
| OPTICS |
| Lens assembly is made up of a 3mm tempered safety glass sealed to the lens frame with silicone sealant together with an underlay of a pattern #12 extruded acrylic lens, mechanically secured. Smooth surface faces outwards. See Product Key for alternate configurations. Optional VF-1 reflectors are available. VF-1 reflectors are made of specular low irridescence, anodized aluminum with a reflectivity of 94% or better. |
