Master Lock140D Solid Brass Padlock with Key, 1 Pack

very sturdy. and my boyfriend used it for a live lock. and we’ve gone back and there’s no rust and it dosent feel weak. the key makes it unlock very smoothly and it’s very smooth.

Can be trusted,great name.

Works perfectly for my pistol case.

I purchased these to lock my Pelican Vault pistol storage case for airline travel. They fit perfectly. I dropped my rating by a star because the edges on the locks are kind of sharp. They are sturdy and get the job done, but lack some refinement.

Worked good for my guncase to get through TSA at the airport.

I have had experience with this model of Master locks before, having purchased a package of three keyed-alike locks from a home improvement store for use on three hose bib locking devices that required padlocks to function. But just now I needed more locks, because neighborhood disturbances (water theft, vandalism by running water full blast unknown by the homeowner until later) caused me to decide to secure all hose bibs.Anyone who has had water softening installed knows that the original bibs pipe soft water after the work is done, and the installers add a new hose bib branching from the incoming water line next to each old and now soft-water hose bib. My three, therefore, turned into six. The original three I had used on the soft-water bibs were, as it turned out, fairly cheesy and not nearly so secure as I wanted, so I bought six new ones plus a pack of four (no packs of three were offered) of these locks to allow me to lock all six devices onto the bibs. (As it turned out, this pack of four locks from Amazon was cheaper than a pack of three at the nearby home improvement store, so I was not the loser.)These locks are quite good, not the most robust locks available but entirely suitable for the task. Any lock used outdoors should be carefully lubricated periodically with an appropriate product and should be kept out of direct weather insofar as possible, but with care and occasional maintenance, should last a long time.

The standard of all locks.

I spent a while researching locks in an attempt to find the smallest lock for my Pelican V200 case. I was hoping to find something with a slightly smaller body since no lock on this type of case is going to prevent someone from opening the box if they really want to. None of the "30mm" locks had the right dimensions, either they were a few mm too short or 30mm too long. These locks click into place with no wiggle room which is fantastic as they don't rattle around or allow someone to open the case 1/4"+ like the typical 1"-1.25" shackle locks.My use case is indoor so I can't comment on weather resistance. The only negative I can come up with is the locks only come with two keys. Buy one lock, get two keys, buy four keyed alike, still only two keys. Most of the junk import locks come with two or three keys per lock which is unnecessary, but it would be nice if masterlock could include four keys when purchasing two or more keyed alike locks.
