One Of The Most Important Considerations When Choosing And M15 STS Series Magnum Is Understanding Which Other Master Lock Padlocks Can Operate With The Same Key.
M1 (K1): Despite Belonging To The Magnum Family, The M15STS Can't Be Ordered To Match The Familiar 4-Pin K1 Key Number Used By Many Steel Sets Including 1KA, 3KA, 5KA, M1STS & M5STS KA.
K6000 (W6000): The K15 Keyway Can Put Inserted Into All 5-Pin Pro Series Locks But Not Vice Versa.
K7000 (W7000): K15 Keyway Is Not Compatible With Master Lock Van Door Locks Nos. 6271 & 770LHC.
Q: How Does The M15STS Compare To ProSeries Locks?
A: The No. M15STS KA Is An Impressive Commercial Magnum Padlock, But Master Lock's Pro Series Offers Capabilities That Go Beyond Physical Size As They Come In A Variety Of Shapes, Sizes, Body Materials, Weather-Protective Designs And Shackle Shroud Security.
Q: When Should You Choose An M15STS Padlock?
A: Choose The M15 STS KA Padlock When You Want An Oversized, Heavy Duty Magnum Set But With Its Own Dedicated 5-Pin Commercial Key System. A Larger Padlock Isn't Automatically A More Secure Padlock. The Best Choice Always Depends On The Entire Security Application, Including Shackle, Hasp, Mounting Hardware, Cylinder & Environment.
