These pins for safety work great on both my trailers for securing the latch, I they fit fine and the latch is large enough to grab and maneuver easily.

If you have a lot of trailers, or are like me and lose these, this pack of 8 trailer coupler pins is a must have. They seem to be made well, easy to use, and a standard size for hitch couplers. They are painted black, likely to aid with avoiding deterioration in the elements. Overall they get the job done.

5/16 pin but paint makes it thicker. It would be a lot better if it wasn't painted. it would be easier to see when you drop it and not so tight in a 5/16 hole, so I gave it 4 stars. It seems to be good quality and the bail works well and seems to be durable too. It is pretty long (about 4 inches) so it should fit most hitches as long as it has a 5/16 or bigger hole. I didn't really need 8 of them but it is nice to have extras. Good value for $17.

If you are going to tow trailers behind your vehicle that utilize a ball hitch, you need these. For some unknown reason, these always seem to be hard to find locally. These come in different sizes. A narrower one and a thicker one. These are the narrow ones so they should fit any hitch. They seem durable and well made. They are easy to fasten and remove. They keep your load secure.

Wanted some replacement coupler pins for my mower. I tend to tow a yard trailer that I load with debris, the couple pins worked as expected. With some to spare, I see no problems with using with latching my trailer with my ATV as well. Simply leaving the pin with the mower and ATV where there are no worries about misplacing my single pin. Product works as expected.

Quality of the pins is very good. Clasp easy to use and stays in place very snug.My issue is that I ordered the wrong size for my immediate need, but keeping these as I do have other items that I can use this item form.I am going to order bigger pins with my next order, but am making sure I order from same manufacturer so I get the same quality of the couplers.
