It is heavy duty and just the tool I needed. I have some very large windows over 6 feet tall with brick facia that are over 16 feet above the ground to the base of the windows. I quickly modified this tool by swapping out the pusher plate with one for a 10 Oz cartridge. The screw thread on the push rod is 1/4 - 24, so if you can plan ahead of time, you can get the appropriate sized nuts to adapt it. I used two pieces of duct tape to secure the 10 Oz. Pusher plate. A piece of duct tape will also hold the cartridge in the larger carrier. I would suggest an extended nozzle for an even better job to address the thickness of the larger carrier. New Norn does sell an adapter for the 10 Oz cartridges that I am sure is equally well made. I was looking for the maximum of reach and reduced weight for my needs. I finished my tasks in under two hours. Outstanding tool! Big problem solver for a DIY guy.
