Question: Do I need another piece of hardware to use this lock? Can this be used by itself on the back of a moving truck rental?
Document: These are the same locks as the 6271 but better, the 6271 has a die cast body these are solid steel. Same keyway and mechanism. body is made by American Lock but lacks the threaded hole on the back to permanently mount the lock to American locks hasp. Pair this with Master 770 hasp. No hardware or instructions come with the hasps, get regular grade 3/8 bolts as long as you need. 1" and big body washers like 2".
this used to be a good lock when it was made in the USA. I still use one that is a marvel of precision. Now that it has been outsourced, the cylinder is a loose and sloppy fit in the body. It is likely that his indicates a slide hammer would extract the cylinder with no trouble at all. I would not use this lock without a barrier to deny access to a screwdriver or slide hammer.
Obviously the Amazon computer system doesn't recognize the fact that replacement/exchange of two locks that are keyed alike means that you need TWO NEW LOCKS, KEYED ALIKE or a single lock that is keyed like the ones originally purchased. I don't expect Amazon to have record of the key code of my original order, but they should replace a matched set with another matched set.
Ordered two locks, keyed alike. Received the locks, they were in fact keyed alike, but one of the locks simple didn't work properly. The tumbler barrel would turn only partially and only occasionally. I tried all sorts of jiggling and moving the key in different ways. There is obviously an internal problem with the tumbler on one of the locks. Went back online with Amazon and ordered an exchange of the items.
Now before I start, remember ANY lock can be picked or broken if someone has the kills or the strong desire. Having said that I love this lock. I used it on my trailer and it worked great. It prevented someone from breaking into it one night (scratches all over it), they did do damage to the trailer, but thanks to these locks they didn't steal anything.
A great lock but wish keyhole area was armored with hardened steel. It is brass and could be drilled out. Use a strong welded eye for this.
I use this on my band's trailer to keep out thieves, potheads, pedophiles and other ne'er do wells. It is impossible to break into.
This is the same type of lock been using on my home vault for many years, thus was well aware of it's capabilities. Purchased this lock for mounting on outside storeage shed. Had originally planned on installing two of them. But after mounting this lock and heavy duty hasp could see that there was no need for a second.
I simply cannot believe how solidly these padlocks are built! Just looking at one would make a criminal run in fear. They look just like the picture, all you see is a solid &#34;hockey puck&#34; made of steel. Yes, you cannot use them on everything you would normally padlock but if they will work in your situation, get them, you won't be sorry.
lock did not fit onto the hasp I got it for.also was not sure why the lock is not the same thickness top to bottom.
Answer: yes
