As A General Rule, The Shortest Shackle That Comfortably Fits The Application Is The Most Secure. But Sometimes, You Simply Need More Height And The Master Lock No. 7040LJ Features Almost 3-Inches Of Vertical Clearance, The Tallest Shackle Available In ProSeries.
Q: Is There More Key Safety With A Keyed Different Lock?
A: There Is Already A Tremendous Amount Of Key Safety Built Into Master Lock's Pro Series K6000 Keyway, Which Encompasses 24,000 Factory Key Changes With Numbers Spanning 10G Through 34G. But Yes, The 7040LJ Will Likely Have An Uncommon Key Number.
Q: Is KD More Secure Than KA?
A: The Physical Construction Is The Same, The Difference Is Access Control Not The Strength Of The Steel Body Or Shackle: Keyed Different Locks (7040LJ) Limit Operating Keys, While Keyed Alike (7040KALJ) Allows The Same Key To Open Multiple Locks.
Q: When Choose Weather Resistant Vs. Weatherproof?
A: The 7040LJ Is A Weather-Resistant Steel Lock That Is Finished With A Chrome Rust-Proofing To Help The Lock Perform Outdoors. Where A Lock Will Be Continuously Exposed To Water, Road Spray, Dirt, Ice & Salt A Covered "Weatherproof" Padlock Is A Better Choice.
