IP66/67Federal Signal's Model WV450X Hazardous Location GRP strobe light utilizes the latest technology in non-metallic housing construction. The housing of the WV450X is comprised entirely of Glass Reinforced Polyester (GRP) which makes the product corrosion free and lighter than a comparable metallic fixture. This also makes the product safer, and "maintenance-free" by elimating the need to regularly inspect the flame path. An electro-polished stainless steel dome guard is also provided for protection of the glass lens in the event of accidental impact.Two versions of the WV450X are available. The "D" version of the product comes standard with a stainless steel mounting bracket for wall mounting or fastening to a vertical surface. Two holes are tapped for M20 pipe thread in the bottom of the product allowing for field gland connection. The "E" version of the product (WV450E) includes the same features as the WV450XD, but incorporates a junction box with three M20 tapped holes on the very bottom of the fixture. This junction box is designed to house field terminations and through going power supplies.
