Maybe think of it this way. Most full sized V8 4x4 pickup truck engines only deliver around the mid 300lb range in ft lbs of torque at the optimal RPM. Personally I would think that other parts inside the lock that you used to hook onto for pulling would hit their shear point before you hit the 1000lb mark.
I'd have to look back at my info, but I know during testing that the master pro series padlocks with boron alloy shackles and ball bearing locking setup failed somewhere in the 1000lb range. I'm not sure where in the 1000 lb range they failed at, it could have been upper 1000's but as I said I don't recall for sure. I do know that this was pulling against very hard yet somewhat elastic shackles, larger bearings than the bilock, and steel internals with a laminated body under those pretty plastic covers.
Personally I think 1000lbs is alot of resistance to pulling for a qcc core. I wouldn't hesitate using any bilock product to secure my home, faimily, and precious items
For the best book out there on high security locks and their operation, take a look at amazon.com for High-Security Mechanical Locks An Encyclopedic Reference. Written by our very own site member Greyman! A true 5 Star read!!
