Master Lock 875D Heavy Duty Outdoor Combination Lock 2, Brass Finish

I've had this for 2.5 years outside on my boat (freshwater) and while it has seriously rusted, it still works and the numbers rotate smoothly and it locks and unlocks as it should. It does not offer the absolute highest level of security - it is made largely of zinc so you could melt it, or try the combinations - but "locks keep honest people honest" as they say; if you need serious security then don't buy a $18 lock. Good value for the price.

Very very hard to spin number s to unlock completely useless I threw it away don’t buy this is garbage

This is a high quality lock that I used on shipping containers. It was nice to have several with the same combination. They may seem expensive but you get what you pay for. I don’t mind paying up for a quality product like this.

The locks is very sturdy, the number wheels are easy to read and spin, and I love the easy combination setting procedure. However, because of the way to you set the combination, you cannot just roll the numbers while the lock is open. Our use is on a chain on a gate. If you leave the gate and lock open for any reason the actual combination has to be left on the lock; you cannot spin the numbers. So, if our gate is left unlocked, anyone who knows this can just look at the numbers and know the combination. I hope that makes sense. Another illustration is if you leave your gate open so someone can get in then you ask them to lock the gate on the way out, they see the combination and have to jumble the numbers for you when they leave.

went w this as a trial to avoid a $350 pool gate lock. this works FANTASTIC!

Once you compare this model to the less expensive version, you can see that this one is better built and smoother in operation. My older on stopped working due to exposure to the weather and basically you could open it without the combination, which is not good. Hopefully this more expensive model will stand up to time. Make sure to test it frequently to make sure it is locking as it should.

Why did you pick this product vs others?: This is a great lock for the price.

This lock is an absolute joke. The quality overall feels cheap and pretty poor, especially compared to some of Master Lock's options (even cheaper ones) I was hoping this would be an upgrade from their 175D, however it is significantly less secure. I was able to decode the wheel within 2 minutes after randomly setting a new combo. The combo can be figured out by adding pressure to the shackle and then feeling for the play in each dial. At times the dial would spin and only stop once it reached the correct number. This is functionally flawed design, it is not secure as it can easily be bypassed without a tool and just a minute or two of time. I am returning this useless lock and going with another 175D as they have improved the tolerances and you need to have a tool to bypass the lock. This doesn't even require a tool, I am disgusted and disappointed in this atrocious design. Do not buy this lock! I found a video after looking up if my lock was just unlucky and had poor tolerances, the lock picking lawyer has a great video that will turn you off from this lock. This lock is only good for a little trick to show your friends how you can open a lock with a random combo.

Achei o mecanismo muito fraco, frágil, dá muito 'jogo' quando se manipula as engrenagens. Totalmente abaixo de minhas expectativas. Definitivamente NÃO RECOMENDO

I bought this lock for my strata garbage room. The lock looks very sturdy and solid. The combo turns smoothly.

Item as described. Fast delivery. Well packed.

Great value heavy duty combination lock with brass finish.

Worked for a month then stopped closing
