Great Product
Just what I needed. Sturdy and well made. Not much else to say about a barrel bolt. Works as intended and the price was ok.

Strong hardware.

Standard.
Inexpensive. Gets the job done. Decent quality, but not great. Works. I have seen better, for sure. But, hey...if it works and saves money, why not? If you are looking for a budget buy to serve the purpose, this will do. Good quality for the price, but again, the more expensive ones are better... and more expensive.

Sturdy
Instillation is tricky. I’m not able to secure the latch because of how I installed it but it’s sturdy enough and keeps my dog from escaping his cage.

I was pleasantly surprised with this item. The price is almost a steal considering the size and construction. I like how it's coated with weather guard because I used them outdoors in Canada. Comes with screws for installation also. Fast delivery. Would buy again if they hold up through this coming Winter, but time will tell.

It is a very basic lock, easy to install, a little on the loud side, but gets the job done.

I needed a slide latch lock and did not know what to buy. I purchased two different models here which cost approximately the same price. This lock is good, it's easy to install and does the job. However in my opinion the "Finenic Door Serenity Slide Latch Lock" was a better more solid and sturdy product.
