Master Lock 3-1/8" Wide Disc Padlock, Heavy-Duty Stainless Steel, M50XKA | Discus Lock For Storage Units, Sheds and Weather-Resistant Security, Shrouded Tough-Cut Boron-Carbide Shackle, 4-Pin Cylinder

Heavy duty lock. Made with quality metal for high performance. I use it on an outdoor storage unit in WI and it has held up to two years of rain, snow, and whatever else. Locking mechanism works as well now as when I first put it on. I did notice some scratches on it last I went to my unit. I guess someone tried to cut it off and couldn’t. Definitely recommend this lock to keep your things safe.

These are great locks I use them a lot

Really heavy duty and solid which is what was needed for my situation. Bigger than expected but worked fine for my purposes. Not the cheapest thing but if you need to protect your possessions, you cannot go wrong with this.

I live in Michigan and I purchased the Master Lock M50XKADCCSEN Padlock, Magnum Stainless Steel Discus Lock, 3-1/8 in. Wide. I have had this lock just over a year. It has been through the ringer with the crazy weather that we have had last summer and winter Ice storms. I have an outside storage unit that I use this lock on. Every time I went out last winter, I have never had one problem unlocking the lock. Good lock great price.

Good lock. But did not fit on the roll up door latch/lock system of the UHaul i purchased it for.

Been using this lock for a while now, and its the most solid padlock I've owned. The construction feels extremely durable and has help up well outdoors without showing signs of rust or corrosion, even after exposure to Florida's rain, sun, and humidity! It's well-made, thick, and sturdy. No jamming!

Seems to work well to secure my storage unit in my apartment. Make sure you measure the width of what you’re locking so that the shackle opening of this lock fits properly. I like that the shackle is mostly hidden when locked so that it resists bolt cutter attacks. I was using a basic padlock and a thief cut my previous Master lock with ease due to an exposed shackle. Can’t speak on the weatherproof features since my lock is indoors. But I do appreciate the key hole cover to prevent dust from seizing up the lock.

DO NOT BUY! If I could give -5 stars on here, I absolutely would. The key snapped in HALF and the keyhole did not budge a milimeter...it stayed locked with half of the key stuck inside! I called several locksmiths, and most of them did not want to work on it. The locksmith who eventually worked on it charged us close to $500 in fees to remove this accursed lock from our storage unit. They told us that the lock stopped working properly because the internal spring mechanism broke. WHAT?! Isn't this supposed to be heavy duty?!?!? I will NEVER buy this style of lock again—and now I don't trust ANY Master products. Master should be ashamed of such shoddy quality. They should be paying customers damages for such gross falsification of their product specs. Customers like me lose $$$ in the end and yet Master makes bank. Unacceptable. This needs to change!

Lock is not safe to use, because of its design.

Estos productos de la marca son muy reconocidos por su durabilidad y resistencia. Y al parecer todo indica que la marca sigue cuidando esa misma calidad a traves de los años.

Très robuste

Un cadenas très solide et résistant pour l'utilisation sur une unité d'entreposage.

Ya he usada la marca con anterioridad y me ha dado buenos resultados y buena durabilidad. Son fialbles. Desgraciadamente a mi caja milwaukee no le quedo pero le buscare otro uso ya que es un buen candado.
