Master Lock - Four (4) High Security Pro Series Padlocks 6121NKALJ-4 w/BumpStop Technology

Very nice locks. The mechanism is finely machined. One reviewer commented that you need to pull the lock open. I believe this is only due to the water/dust cover that fits so snug. I sprayed a heavy dose of silicone lubricant into the key hole. Not one drop came out around the shackle. When I turned the lock right side up, about 2 ml of lubricant fluid poured out through the key slot.

It are so good

Good value

And smooth locking/sliding mechanism. Well built. Only just received but SHOULD hold up in wet humid Southeast Louisiana.

Good value

These are some solid locks that are weather protected. They work great on my toy hauler and other trailers.

These locks are great quality and the keyed alike feature makes them even better.
