Instructors Chris Collier and Nate DeMarse demonstrate the use of through-the-lock techniques with a Rex Tool, but in this video Through-the-Lock techniques fail. Having a systematic plan-of-attack for forcible entry operations will cause you to immediately revert to another option when "Plan A" doesn't work or isn't working in a timely manner.
Chris attempts to manipulate the lock with no success. After a few attempts, Chris and Nate revert to conventional forcible entry operations on an outward swinging door to complete the forcible entry operation.
Once again, the entire video is only 1min 14sec in duration (including title and exit pages). The conventional forcible entry operation is started at approximately the :40 second mark in the video, and only takes approximately 30 seconds to force the outward opening door with a mortise lock.
Stay away from the "whiz-bang, new techniques" that are out there, and more coming every day. This forcible entry evolution has been in our business for almost 60 years, and works EVERY TIME. There is NO NEED to reinvent or change techniques that work EVERY TIME to techniques that are VERY LIMITED in scope (power saw/framing square technique for panic hardware for example).
The techniques shown here will force panic hardware VERY EFFICIENTLY, and much quicker than plunge cutting and trying to locate a framing square. Also keep in mind that one $3.00 slide-bolt (found at any hardware store) will completely shut down a plunge-cut/framing square operation.
