Master Lock 6271NKA 400K001 Bump Stop Padlock

The Bump Stop Cylinder Of The 6271NKA-400K001 Was Developed By Master Lock To Provide Additional Protection Against Lock-Bumping Attacks As The Upgraded Security Cylinder Complements The Reinforced Lockbody And Hidden Boron Alloy Shackle. 

Q: Is Bump Stop Necessary For Every Installation? 
A: Not Necessarily. That's Why We Continue To Offer Both The Standard (No. 6271KA) And BumpStop (No. 6271NKA) Versions When You Want To Add Greater Cylinder Resistance. 

Q: Does BumpStop Make The 6271NKA Pick-Proof? 
A: No Padlock Can Be Described As Completely Pick-Proof Or Attack Proof. Master Lock's Bump Stop Technology Is Specifically Intended To Increase Resistance Against Lock Bumping, Which Is A Key Jamming Attack Which Looks To Loosen The Cylinder Pins.
