Works well and very well made



by:

As expected. Super stout ring. Very fast shipping



by:

Great quality. However, the mount will not fit in the standard 8 inch channel of the Demco actuator. I will have to either grind off the sides of lunette or try and bend the mount to get it to fit inside.



by:

Doesn't fit in the channel that was purchased with the 40,000 lb lunette eye.



by:

Works great.



by:

Heavy duty works great. Just have to buy the bolts separately is the only downside.



by:

While the description says it can be used in the drop or rise position the product itself says otherwise. Also the locking mechanism seems like it would be easy to defeat. With a heavy trailer it would just bend up and at most they wouldn't be able to close the latch. They could still drive off with it and worry about that later

The quality was top notch. Can’t beat the price on it. Welded in great and hauled my excavator, which weighs 18k, just fine.




by:

Quality product, but it's advertised as an 8 position. But it's only a 4 position. I assumed I could turn it upside down for the other 4 positions. But the directions clearly warn you no to use it in the inverted position. So I bought the 25,000 lb eye because it's only a 2 bolt eye. And it is wider than the channel by 1/8". Still usable but not without modifications which I'm sure voids any warranty.



by:

The ring is wearing extremely fast!! Much faster than any other ring we have had. DON’T BUY THIS LUNEtTE RING! Our trailer weights were all under 15,000 lbs.



by:

Hitch arrived packaged well and it performed exactly as expected with fast shipping.
