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.

looks very durable, as advertised.
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.
Arrived in 2 days in perfect condition!
This plate is working great!
Looks like great quality, can't wait to use it! Simple to assemble and install.
Recieved in perfect condition. Will use in a few months.
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.
Fast delivery and well packaged.
Great service and super great prices.
Great product no grease!!!!!
The fifth wheel hitch from B&W delivery was seamless. I enjoyed working with etrailer. I will be using them again. Vert easy!
Seems like a good product but was never used. Only did bumper pull tows.
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.
Super smooth without the mess of grease.
Looks to be of good quality. Purchased this for a new 5th wheel install.
You were great help with setting up my hitch.
Ordering was easy and tracking the delivery was excellent. Everything was received as expected and looking forward to a great camping season.
Prompt delivery and no damage.
All our RVs get Snap pads.
Easy to install. Amazingly quick shipping. Product was perfect and exactly as described in video
Easy to use. Better than using grease on the hitch.
An easy ordering process and super fast shipping.
Awesome I am loving it. I had a cheap knockoff prior to this and was ready to go back to grease. Then I said well I’ll get a good one from etrailer and see if it makes any difference. It is night and day. Thanks to your chat team and their help.
Plate allows us to tow our fifth wheel with no grease at all.Nice to have no mess at all,would recommend!
Very good lube posts. Easy to install and remains on the king pin after unhitching.

Slapped this lube plate on the King Pin and basically forgot about it! Summer 2025 we hauled our Grand Design 5th wheel over 10,000 miles and it worked as expected - Perfectly!! Thanks etrailer and Curt.
