This video is from Mike Perrone from FDNY Ladder 175. Mike has developed a forcible entry door prop for firefighters and he has a long list of departments and training companies who are using the door.
He has several videos on the Multi-Force door and forcible entry techniques. There is some really great stuff on here that you should share with your crews and department.
Check out the videos and then go see Mike on his site at Firehouse Innovations.
