I dont have the closed length details to hand but will post them either this evening or tomorrow.
The website you detailed has been out of action for around 2 1/2 years we released a new website 2 1/2 years ago which was closed down around 9mths ago so i dont know why that is still around the internet.
I hope this helps.
The difference is the material and build of the pole, i personally dont find a three section pole a problem as i see it the ground floor poles that are about by excel do that job perfectly so thats another reason i did not design and build a ground floor pole, i know that their will be those that say they use a 18or 20ft pole for everything but i did not design this pole just for houses or just for commercial.
i designed it for window cleaning and after the testing both in a lab and in the field i believe i have it just right.
