## Description

The Master Lock 140Q Solid Body Padlock with Key features a 1-9/16in (40mm) wide solid brass lock body that is strong, durable and resists corrosion. The 1/4in (6mm) diameter shackle is 7/8in (22mm) long and made of hardened steel, offering extra resistance to cutting and sawing. The 4-pin cylinder prevents picking and the dual locking levers provide resistance against prying and hammering. The Limited Lifetime Warranty provides peace of mind from a brand you can trust.

Review: Nice padlock - EXACTLY what we needed and as pictured/advertised. Received quickly and in excellent condition.
Review: Great Step Up for Beginners - Perfect for Yellow Belt Practice - I’ve gotten pretty decent at picking standard locks—usually, I can get through them in under 10 seconds. However, this Master Lock 140 definitely puts up a fight! It took me about 45 seconds to get it open the first time, which is exactly the kind of challenge I was looking for. ​The Highlights: ​Security Pins: Whatever is inside (likely a spool) provides great feedback and resistance. ​Rotation: You can really feel the core movement and counter-rotation, which is perfect for learning how to handle security pins. ​Belt Ranking: If you’re following the LPU (Lock Picking United) rankings, this is a solid choice for Yellow Belt practice. ​I’m sure I’ll get my time down as I get used to it, but I highly recommend this for anyone moving past the absolute basics and looking to practice their "feel" for security pins.

## Questions & Answers

**Q: Will this lock fit on the Pelican 1750 rifle case?**
A: Sure will... like a glove! It helps to put them on upside down for easier removal. Also, as a side note if using these for flying. There's NO SUCH THING AS A TSA LOCK!!! I specifically took my case with these locks (empty) into Detroit Metro a week before my flight, spoke with TSA and Delta, both said there's no TSA approved lock since you sit there while they screen it and approve it, then you and ONLY you have the key. They both said these locks are perfect. I asked what happens if they need to check the contents later. They recommend putting a tag with your cell # and flight on it so they can call you before using the bolt cutters. If you're already on the plane, well, don't expect the locks to be there, but to answer your question... yes.

**Q: can this be used for lockers? my son goes to summer camp and they need them for the lockers. also, how heavy is this?**
A: I guess it depends on the size of the latch your son's locker has.  I use mine for my locker at my gym.  It's a pretty hefty lock -- really solid.  If I threw it at you, it would really hurt.

**Q: Is there only 2 keys of 4 keys, you know, one for each lock?**
A: This set comes with at least 3 keys (maybe 4).  All I can remember is that I had three sets of keys and I can't honestly remember if there was a fourth.

**Q: Are these good for outdoor use?  The padlock I'm currently outdoors using has gotten rusty.**
A: No. The shackles and mechanism rusted almost immediately. They are junk I can recommend the similar Abus padlocks for outdoor use.
