Perfect for Locking Kayak Perfect for Locking Kayak
Size: 2 inch wide
I’ve been looking for YEARS for a solution to locking my kayak to a public rack. I don’t drive so I really wanted a way to leave my kayak at the public launch for a whole season. I’d seen sit-on-top kayaks locked through their scupper holes, but there were no holes big enough on my sit-in yak. I figured I’d give this lock a try because of the length and the fact that the shackle could fully detach. Turns out, it fits PERFECTLY through the hole for the carry handles on my Pelican kayak. I’ve had it out there for about a week now in a very busy area of a public park and no one has messed with it yet! So far, the locking/unlocking has been extremely smooth. I will update if it gets rusty or otherwise harder to use. I know this review might not be that relevant to most users of this lock, but I hope it helps someone who was in my former predicament. I’m using it with this chain: Master Lock 73D 3-Feet Hardened Steel Chain, Green Sleeve https://www.amazon.com/dp/B000AYH8MO?ref=yo_pop_ma_swf

Good, sturdy locks
Size: 2 inch wide
These locks feel decently sturdy, and we got them just to secure some cabinets in a shared area. Easy to use with the keys provided, and it's nice that they are adjustable on the length when locking or unlocking. Decently priced, I'd say worth it if you're not looking for anything super heavy duty.

Little awkward but alright lock
Size: 2 inch wide
Didn't work for what I needed it for, but it's an alright lock. The positioning of the key when the shackle is all the way up is a little awkward. I imagine its nice and durable and the plastic helps it resist weathering. Good for larger lock holes.

Works well for my purpose.
Size: 2 inch wide
These are perfect for securing closed handle cabinets. They do not work on my double door storage cabinet because the handles are open ended and go from wide to narrow. Takes little effort to slide them off. Not the fault of the lock. It's sturdy and slides easily. Great for a cubical office environment where you just need a little extra security. I would not put it on a public storage unit or anything that is vulnerable to mischief. The lock is spring loaded and you must have the key pressed to the unlock position to slide the lock either way (opened or closed).... which means the person who closes it must have the key. Not a concern if this is a personal lock but if it's a community cabinet (like coffee or office supplies) such that you want the 1st person in to open it and the last person out to close it, then keep in mind both must have a key.

Very helpful
Size: 2 inch wide
Having to use these on the pantry cabinets to help keep a dementia patient from overeathing. That may sound bad, but we have 3 meals a day, plus snacks in between. She is at a healthy weight, but starting towards dementia. Now, when she gets up in the middle of the night, she can't get a chocolate bar or crackers and have them all in her bedding.
