The famous Hixon prism poles are constructed of durable anodized aluminum tubing with a solid brass 5/8"-11 threaded stud on top. The only pole with one-handed locking, allowing easy setting of predetermined heights. The poles have red and white stripes at 1' intervals. Permanently affixed level block has 1" recessed bubble for protection and easy adjustment. Comes in 1', 8', 12', 16' and 25' extended lengths with no graduations. While using the 1' pole, you won't have to stand up to keep checking the bubble to set a point - the bubble is where you need it. Use the 25' pole to get over small trees and bushes. The unique universal Pole Point uses a replacement plumb bob tip as its point.
