Rectangular brass padlock
This Master Lock padlock uses a rectangular brass body with a laminated finish and a 4-pin cylinder. It opens with key number 712 and is sold keyed alike so multiple units share the same key. The shackle is steel and the lock is rated weather resistant. It suits doors, gates or storage units where a single key simplifies access.
Keyed-alike convenience
All locks in the 712 series turn with the same key, removing the need to carry a separate key for each point. No control key registration is required and the cylinder cannot be rekeyed. The package includes the padlock only; no extra keys or mounting hardware are supplied. This keeps key management simple for one person or a small team.
Four-pin security limits
The 4-pin mechanism provides basic deterrent against casual tampering but is not rated high security. The 9/32 in shackle diameter and 3/4 in clearance fit standard hasps and chains. The brass body resists corrosion in outdoor conditions. Buyers who need pick resistance, a thicker shackle or a rekeyable core should choose a different lock.

Questions about this item
Will the 4-pin cylinder or the brass body need replacement first?
The 4-pin cylinder is the serviceable part; the solid brass body is laminated and weather resistant, so the lock mechanism will need attention before the body does.
What stops the shackle from being forced after prolonged attack?
The 9/32 in steel shackle and 5/8 in clearance set the physical limit; the lock is rated standard security, not high security, so sustained force will defeat the shackle before the cylinder.
Does the brass finish or the keyway bind after a day of outdoor use?
The laminated brass finish resists weather and the Master K1 keyway operates without electronic parts, so neither heat nor continuous exposure causes binding during all-day operation.
