All 2000 Series Beacons offer the following standard features:

• Fully enclosed base: Sturdy polycarbonate base or cast aluminum base, all strobe power supplies are encased within the base itself for added protection against moisture and vibration.
• Silicone coated power supplies: For added protection against the elements, all strobe power supplies are double dipped in a uniquely formulated silicone mixture before being secured into the base enclosure.
• External flange mount, internal "secure" mount, or pipe mount all in one: All 2000 Series strobe beacons come standard with a base that allows you to either: (1): 3 knock out holes for permanent "secure mount", (2): a sturdy built-in flange to externally mount beacon (except on cast base model) (3): a built-in 1" pre-threaded pipe mount.
• New optic, interchangeable domes: All 2000 series strobe beacons are now equipped with the newest state-of-the-art single lens optics to optimize their light output. All beacons utilize the same low and high domes for ease of interchangeability.
• All six safety colors are available: amber, clear, blue, red, green and purple.
• Easy access for modular parts replacement: After removing two screws from the outer dome, you are able to easily access either the flashtube or the strobe power supply without removing the beacon from your roof.
