Outside diameter is 9" and the unit weighs 235 pounds. Rated for a maximum load of 150 pounds. Also available is the matching Nycoil with a 1.25" inside diameter and a 3/4 HP Gast compressor (120V 60Hz). The complete package with the mast, compressor and Nycoil is SOLD. Total shipping weight is about 400 pounds.
The customer drawing and wind load capacity chart is available at the Will-Burt web site.
Telescoping Mechanical Masts
The heavy duty mast shown below was originally designed to support three large spotlights at 20 feet. The main unit weighs about 110 lbs and is 6 feet long collapsed. The unit is supported by four legs that fold out of the unit. U-stakes are provided to anchor the unit to the ground. Three sections are extended one at a time with a ratcheting rack and pinion drive. The legs are easily removed for mounting directly to a fixed structure such as a trailer. Our inventory has been depleted, but these are available from Tim Clark glengar@verizon.net.
