Security Padlock Hidden Shackle
The Master Lock padlock uses a concealed shackle design that protects the 3/8 inch diameter boron shackle from cutting tools. Its zinc body with chrome-plated finish resists weather and corrosion. The 6-pin American K700A keyway provides high-security locking for gates, containers and storage units.
Alike Key System Limits
All locks in the alike series open with the same key number 13033, so one key manages multiple points. This convenience means a single lost key compromises every padlock in the set. No control key registration is required, but the system cannot support master-key hierarchies or individual key changes without replacing cylinders.
1-9/32 Inch Shackle Height
The 1-9/32 inch shackle height and 1-23/32 inch shackle width define the maximum hasp or chain link thickness the lock can engage. Measure the mounting hardware before purchase; thicker hasps will prevent the shackle from closing fully. The body measures 1-1/2 inch high by 2-7/8 inch wide for reference.

Questions about this item
Should I choose the alike-keyed version or a different keying option for multiple locks?
This padlock is supplied keyed alike and opens with Key No. 13033, so every unit in the pack works with the same key — ideal when you want one key for several locks.
How does the hidden shackle design affect real-world security?
The hidden shackle leaves only 1-9/32 in of shackle exposed, making bolt-cutter attacks far harder while the boron shackle and 6-pin American K700A cylinder resist picking and forcing.
What does the American K700A keyway mean for key control and duplication?
The K700A keyway is a restricted Master Lock profile; keys can only be cut by authorised locksmiths, and the alike system uses Key No. 13033 so duplicates stay controlled.
