The padlock measures 1.5 inches in body width with a 0.75-inch shackle and a shackle diameter of 0.28 inches. It ships without keys, making it compatible with the Master Lock Universal Pin System, which allows a handheld keying tool to set the pinning configuration on site. Licensed locksmiths, facility maintenance techs, and security-conscious contractors install this padlock where master-key or rekeying capability is required without sending locks to a shop.\u003c\/p\u003e\u003cp\u003eThe 3UP fits into commercial, industrial, and institutional applications where a single keying platform manages multiple locks across a property. Typical install scenarios include equipment rooms, storage lockers, utility enclosures, and access-controlled gates. Because no keys are included at the factory, the end user determines the key combination using the Master Lock Universal Pin System and keying tool 376. Compatible key blanks are the Master Lock K1BOX or the Ilco blank M1.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRekeyable on site using Master Lock handheld keying tool 376 without sending to a locksmith shop\u003c\/li\u003e\n\u003cli\u003e1.5-inch padlock body width fits standard hasp and latch hardware\u003c\/li\u003e\n\u003cli\u003e0.75-inch shackle clearance accommodates typical locker and gate hardware\u003c\/li\u003e\n\u003cli\u003eShips without keys — key combination set by installer using Universal Pin System\u003c\/li\u003e\n\u003cli\u003eCompatible with Master Lock key blank K1BOX and Ilco blank M1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use within the Master Lock Universal Pin System.
