This 90 degree telescoping boom extension arm will stretch up to 6 feet.
It allows you to spray higher test surfaces (about 12 feet) when performing the AAMA 501.2 test with the Rain Wand 501.2 kit and helps keep you out of the spray. Detachable nylon roller ball & spacer stick maintains the 12 inch distance from the test surface that's called for in the AAMA 501.2. Rain Wand NOT INCLUDED.
