Today we're going to review part number 16721. This is the Curt 10-inch 5th Wheel Trailer Hitch Lube Plate. This will protect your 5th wheel hitch in your 5th wheel trailer when you use this Curt Lube Plate. It's a 10-inch diameter disk that will easily slide onto the kingpin of your 5th wheel trailer and eliminates any messy grease deposits and it will reduce normal wear and tear when you're towing your 5th wheel trailer with your 5th wheel hitch. Again, just to measure the diameter for you. Edge to edge it's going to be right at 10 inches and thickness on it is going to be right at about 3/16 of an inch. Just to show you, here's an example of a .. This is what the kingpin would look like on your 5th wheel trailer.
You just install this onto the kingpin itself and then when this installs into the 5th wheel hitch, it will give you a nice protection between your pin box of your 5th wheel trailer and the 5th wheel hitch itself. You remove it just like that. That should do it for the review on part number 16721, the Curt 10-inch 5th Wheel Trailer Hitch Lube Plate. .
Good solid plate
Since I have a TurningPoint hitch I use a Wedge behind my Kingpin. So it required marking the outline of the wedge and trimming the Lube Plate on my bandsaw to fit precisely on the wedge. So far it seems to work fine. So much nicer than all the grease.
5th wheel hitch and hardware went on truck just as described. Everyone at ETrailer is very courteous, helpful and knowledgable. If you have any questions or issues, they are there to help you. Have dealt with them before and will deal with them in the future as needed. Thanks !!!!
Love the service provided great friendly folks to work with. Very quick response time and
parts delivered quickly. Thank you all and look forward to future orders with you all..
Does what it’s supposed to do. Nice not having grease on the plate.
e-Trailer ships quickly and carries good products. Helpful tech support when needed. I get all my trailer and towing gear here.
Very easy to use, and don't have to deal with grease on the surface of the hitch
Perfect fit on my 2019 Solitude kingpin.
Works great. Saves on having to lube and have grease on everything.

Still working great
Perfect! Arrived ahead of schedule in perfect condition. Great service from E-Trailer!
Very knowledgeable and helpful fast delivery will buy from again
I made this purchase so that I did not have to keep removing my 5th wheel hitch to use my gooseneck ball attachment. This item worked out well and made it much easier to hockup my dump trailer.
Great product!
Works great. Much easier than lubing the hitch constantly.
Works great! I use a similar product on my tractor trailers and I like these just the same. They are reasonably priced, easy to install and last forever! It’s still very important to grease the jaws and king pin but they really preserve the plate and hitch.
Anna was very helpful and the package was delivered next day. That is what I call excellent service!!!! Thank you!!
Works great. Cheap and easy.
Great item. Thanks
I have had one of these on all of my 5th wheels. They are the way to go.
We love them! Keeps things cleaner! Easy to use!
Clean use and still provides great lube action for the fifth wheel
Great product, heavy duty, good heavy welds. Sharp edges, had to grind, but worth it. A lot cheaper in cost than other ones, always happy was price and products from etrailer. Super fast shipping.

The Curt lube plate has held up nicely for more than a year. Weve taken the trailer on 8-10 trips during that time frame.
