The Bump Stop Cylinder Of The 6271NKA-400K002 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.

Master Lock's Current Price Book Currently Lists The "N" Prefix As "Anti Bumping Cylinder Technology" & An Available Built Option For The No. 6271 Series Van Door Lock Platform, While Its Technical Manual Confirms That While BumpStop Cylinders Are Listed As Rekeyable They Do Require Correct Handling Of The Specialized Top Pin When Keyed.
