When I went thought FFI last summer this particular tool was very briefly discussed however the regional fire school did not have one present, I have yet to see one on a piece of fire apparatus. I was curious if anybody on here who may have this tool on their engines and/or trucks could tell me a little bit about it such as its basic operation, pros and cons to the tool etc. I know the name of it and that it is a forcible entry tool but that is about it. Any help is greatly appreciated!
