ABUS 37/55MB50 KA Granit Alloy Steel Padlock Keyed Alike (Code 5544653) with 2" Long Shackle

“I recently purchased ABUS 37/55MB50 KA Granit Alloy Steel Padlock Keyed Alike and I am very happy with my purchase. The lock is made from hardened alloy steel with a tensile resistance of 6 tons, which makes it very sturdy and durable. The ABUS Plus disc cylinder provides the highest protection against picking, which gives me peace of mind knowing that my belongings are secure. The shackle and body are made from hardened alloy steel with black Granit coating for extreme corrosion resistance, which makes it perfect for outdoor use. The disk cylinder is extremely drill resistant, which adds an extra layer of security. The lock comes with two keys, one with an LED light and anti-key duplication card, which is very convenient. Overall is a great padlock.

The Abus Granit lock I bought is being used to chain up my heavy 16 foot tool trailer's frame to my truck frame, and it's been smashed numerous times between the truck hitch and the ashpalt and concrete roads when I hit a big bump or pothole. The outer casing has been mildly abraded away on the bottom and it's scratched up a lot and areas of the finish have been worn off, but despite the stupid level of abuse it gets, it still functions like butter after 5 months of hard use. As the photos show I did realize how I can keep the lock from getting under the hitch, by putting the shackle through one of the safety chains' upper portion. I do keep the lock regularly lubed with a dry lock lube (1yr switched to silicone works a little better) since this is within a foot of the road at all times, and have not seen any significant corrosion so far. VERY happy with this purchase. Locksmith I talked to at one time said he had to cut one of these, and it took him about 10 minutes with a high quality angle grinder and diamond cutting wheel.Update 1yr to the month, this lock is still buttery smooth despite a year of the elements and close proximity to the road, while all the other locks I bought previously have loooong since frozen up and been trashed despite regular lubing, mainly due to rust, which the abus Granit lock appears immune to. I've replaced all but one of my other padlocks with abus granites and I don't think I'll ever buy another brand again unless they stop making them!

There is a reason you pay what you do for ABUS products, especially the disc detainer style such as this one. I used this originally as a box truck lock to my great satisfaction and now use it for a shipping container storage unit. It comes with two keys, one of which has a built in LED light...neat, but ultimately a little pointless... and a key code card for key re-order should that be necessary. The long shackle adds versatility and works well for box truck swing arm locking mechanisms where a shorter shackle cannot be rotated to effectively close. I feel the price is worth it and would buy again if needed. While this type of core CAN be picked by a pro, it will be a significant time investment likely steering them to an easier lock on someone else's stuff. The counter argument is that it says, hey, there's something to steal in here. Look kids, if a thief wants what you have and they are skilled enough, they will get it, you might at least make it as hard as possible if that's how it is gonna go down. JM2C tho

I wanted a very heavy duty lock with MAXIMUM SECURITY. After doing extensive research. I found that the Abus Granit series is one of the most trusted locks. No they are not cheap. You get what you pay for with a padlock. These are hand made in Germany. Abus has a YouTube video of these locks being made. I use it paired with Pewag 1/2 inch 12mm security chain. This chain has plenty of YouTube videos of people trying to cut it. The chain is just as hard as the jaws on a bolt cutter. I use this combo to lock a trailer to a tree in my yard.

Can’t go wrong with ABUS. A great lock company. This lock hangs lower than you would expect with the longer shank.Super secure and beefy!

This product is high quality. Kudos to the seller. Item shipped immediately.well packed. Well surely order again in this shop.

I saw a youtube video (in Russian) of attacks on the 37/55 using a sledgehammer, crowbar, and 42 inch boltcutters. This lock held up fine. The boltcutters left only a dent in the shackle. It feels heavy for its size. And as much as I know about steels and hardening processes, this alloy is a mystery. Still, the shackle has a "ping" to it that indicates tremendous hardness. Yet it stands up to sledgehammer attacks. The black "Granit" finish is slick and appears harder than a good epoxy finish. I have yet to find a tougher lock with an 11mm shackle.

This Lock met the criteria for m outdoor shipping container. It has a beefy shackle and a disk detainer lock with key control to limit the ability for the wrong people to get copies. An Abloy is a better lock then this but they did not have the longer shackle.
