7x7 Practice Lock
Last year I picked up a 7×7 practice lock from LP101 user Mr. Wizard. It is a rather interesting top loading 7 pin lock with a Schlage SC4 keyway. The beauty of the design is that you can change the bitting in seconds, and also limit your access to working on a single pin stack at a time. As you can imagine, the lock can be transformed from a single pin lock to a 7 pin with serrated and spool pins for an added challenge in no time at all. The SC4 keyway is spacious and has ample room for a torsion tool.
A perk of the kit is that it comes with:
- Bottom Pins 7 each of all sizes for Schlage locks cuts 0 -9
- Master Pins 7 each for 2- 8
- Top pins 2 sizes 10 each , 16 security top pins 8 serrated 8 spool in 2 sizes 4 each, 7 extra set screws.
- Springs 2 sizes long and short 12 of each.
All in all it is well worth it if you are looking for a commercial quality adaptive / progressive lock. It has been a great training companion when teaching techniques for novices and more advanced techniques for serrated and spool pinned locks.
