2" OD x 1/4" wall x 1 foot 6061-T6 aluminum Weight per foot = 1.7 lbs
Use the heavy wall mast when your load is greater than 20 lbs at 32 feet. For example, use three sections of heavy wall (all four sections if over 35 lbs load) and one section of 1/8" wall for a total height of 32 feet. Keep in mind that at 20 lbs load plus coax and the weight of the mast, you will need help tipping the mast up. Use a two or three man crew , or use a 6:1 or better brake winch.
