Master Lock

<h3>A Century of Security Innovation</h3><p>Since 1921, Master Lock has been synonymous with strength, durability, and uncompromising security. Founded by locksmith-inventor Harry Soref, the company revolutionized the industry with a padlock design that used laminated steel layers to economically produce an exceptionally strong lock body. Now a subsidiary of Fortune Brands Innovations, Master Lock Company LLC is headquartered in Oak Creek, Wisconsin, where it continues to develop security solutions trusted by millions around the world.</p><p>The brand gained widespread recognition through its famous 1974 Super Bowl commercial showing a blast from a high-powered rifle aimed at a padlock—though the bullet pierced the lock, it still functioned, cementing the "Tough Under Fire" slogan in the American consciousness. That commitment to legendary strength remains the foundation of every Master Lock product today.</p><h3>Comprehensive Security Solutions</h3><p>Master Lock's extensive product lineup serves diverse security needs across personal, automotive, commercial, and industrial applications. At the core of the brand's reputation are its <a href="/436-master-lock-locks-200628">locks</a>, which range from classic laminated padlocks and combination locks to cutting-edge Bluetooth-enabled and biometric models. The company added the combination lock to its portfolio in 1935, a model still sold today, and launched Bluetooth-enabled padlocks in 2015, demonstrating Master Lock's ability to honor tradition while embracing innovation.</p><p>Beyond traditional security, Master Lock has expanded into automotive and cargo control solutions. Their <a href="/436-master-lock-tie-strap-and-clip-10142">tie straps and clips</a> help secure loads in truck beds, trailers, and roof racks, featuring innovations like the StrapTrap system that manages excess webbing. For vehicle security, Master Lock offers specialized products including <a href="/436-master-lock-spare-tire-hoist-20541">spare tire hoists</a> and spare tire locks for automobiles, protecting vulnerable external-mounted tires from theft.</p><h3>Built to Last</h3><p>What sets Master Lock apart is not just product innovation but enduring quality. Customer testimonials speak of locks protecting spare tires during 8,300-mile trips to Alaska and combination locks working flawlessly after 64+ years of service with exposure to the elements. This extraordinary longevity stems from Master Lock's commitment to rigorous testing and premium materials, whether it's high-security shackles on padlocks or UV-treated polyester webbing on cargo straps.</p><p>Whether you're securing a storage unit, protecting tools at a job site, locking down cargo, or safeguarding your vehicle's spare tire, Master Lock delivers the authentic, time-tested security that has made it a household name for over a century. When protection matters, professionals and homeowners alike turn to the brand that literally proved it's tough under fire.</p>

Product Details

The Master Lock 770LHC is a Pro Series high-security combination consisting of the Model 770 hardened steel hasp and the Model 6271 reinforced die cast hidden shackle padlock. Engineered for commercial and industrial applications, this system delivers maximum resistance against forced entry, making it an ideal solution for van doors, trailers, cargo trucks, security gates, and vending machines.

The 6271 hidden shackle padlock features a 2-7/8in (73mm) wide reinforced die cast body that fully conceals the shackle, eliminating the exposed hardware that bolt cutters and pry bars typically target. The stepped-back design integrates seamlessly with the 770 hasp shroud to create a unified barrier against drilling, sawing, and crowbar attacks.

At the heart of the lock is a rekeyable 6-pin W7000 cylinder with pick-proof spool pins, delivering superior resistance to picking and unauthorized key duplication. The cylinder can be rekeyed to match existing key systems, making it highly practical for fleet operators and facility managers.

Key Features:

  • Combination includes: Master Lock 770 hasp + 6271 hidden shackle padlock
  • 2-7/8in (73mm) wide reinforced die cast lock body
  • Hidden shackle design protects against prying, cutting, and crowbar attacks
  • Rekeyable 6-pin W7000 cylinder with pick-proof spool pins
  • Hardened solid steel 770 hasp — 9-1/16in (230mm) long x 4-1/2in (114mm) wide
  • Hasp mounts with six 3/8in carriage bolts, washers, and nuts (hardware not included)
  • Available keyed differently (KD), keyed alike (KA), master keyed (MK), or zero-bitted (KZ)
  • Compatible keyways: Master Lock W6000 and American Lock W600A / W700A
  • Replaces Master Lock 6270 and American Lock A801LHC / A802LHC
  • Designed for severe-use commercial and industrial environments

The Master Lock 770LHC Pro Series hasp and padlock system provides a layered, high-security solution where both components work together to deny access at every attack point. Two keys are included per padlock.
