Padlock with keyed-alike convenience

The Master Lock 312KA-0702 is a rectangular steel padlock designed for users who need multiple locks operated by a single key. Its laminated blue body and standard shackle suit indoor and sheltered outdoor applications where matching key codes simplify access management.

Sustained exposure to weather and force

The steel shackle measures 3/8 in diameter with a 3/4 in height and 1/2 in width, while the body is 2 13/64 in high, 1 9/16 in wide and 1 in thick. The four-pin cylinder and laminated construction resist casual tampering, though the specification notes no weather-resistant rating, so prolonged moisture or salt spray will degrade the finish and mechanism over time.

Verify shackle clearance and key requirements

Before ordering, confirm that the 1/2 in shackle width and 3/4 in internal height fit your hasp, chain link or locker latch. The locks are supplied keyed alike to Master Lock key number 702 with a K1 keyway; they are not rekeyable and do not accept interchangeable cores, so any future cylinders must match the existing key code.

Questions about this item

How much heat does the steel body generate when the lock is exposed to direct sun all day?

The laminated steel body absorbs ambient heat but has no internal power source, so it produces no heat of its own.

What door thickness and hardware are required to mount this 1 9/16 in wide rectangular padlock?

The lock uses a 3/8 in diameter shackle with 3/4 in clearance, so the hasp or chain link must accept that shackle size.

Will the Master K1 keyway on this blue padlock accept keys cut for older Master Lock No. 702 keyed-alike sets?

Yes, it opens with Key No. 702 and shares the Master K1 keyway, so existing No. 702 keys will operate it.
