Could be a little bit more robust, but overall works for keeping honest people honest. Etrailer always has great service and gets you what you need!
Seems to work well. Thanks.
Excellent fit, you would need a torch or a cut off wheel to remove this without keys.
Received 1 day early! Used USPS. Product is heavy duty and great product. I haven’t used yet but impressed. Made in USA.
The lock seems beefy enough. The key is attached to a screw which threads into the tip of the steel shaft. It works.
Looks heavy enough to keep someone from backing under the Gen Y 5th wheel pin box then disappearing with our expensive Luxe 5th wheel. It's bright yellow finish will be easier to see when I'm about to hook up and go, my thoughts on other things at times. All help is appreciated! lol
This 5th wheel lock is very easy to install and to remove...
Build strong, to give you the theft protection you want and need.
Product works great. E-trailer was awesome to work with! Very good communication and quick shipment!
Received my order in 3 days after it was upgraded to the next level of shipping at no cost to me. Great Service!
Where Istorage my cargo trailer sometime when I go back to pick it up it's at different position where I left it no more worries about that now lock and stay
Trailer Security Product was as portrayed. I expect it to keep the honest people. T he simplicity of the key/ lock structure leaves a little to be desired. the lock could be more Technically advanced. I expect it to work as required.Service was excellent and I would consider future purchases if the product was available
I am extreamly satisfied with Etrailer.com Excellent service, shipping time awsome:) I was very happy with the whole order. I willl defintley tell everyone who needs rv , trailer parts about etrailer.com. I live in Sidney Montana, Big Oil Boom now, lots of people live in trailers, and rvs, campers ect.I will always recomend ETrailer.comThank you for being availble :)Have a great day :)
Great product & fast shipping!
The lock was very easy to install! I received the original lock minus a key. I made a call and spoke to Neil, and had another order issued for a replacement lock and received within a week. I am very happy with the product and the service that etrailer provided.
Fits great, seems to fill the bill perfectly. Sure adds a degree of comfort when I leave my trailer unattended for a while.
I think it’s going to do the job I need it to do
Great Locks You can buy them with Matched Keys from Etrailer.com
Received lock today, fits just like it should
Simple, easy to use,does the job.
So far so good for our new 5’er. Little weird how you have to turn key (around - around) to undo the lock but will get use to it.
As always - quick delivery and superior quality. When I have needs for my RV or truck - I look to etrailer first.
Very tight fit. Be nice to include a tag for the keys.
The product and the staff were both great. Very happy with the service.

Same as before. Still like it. While you cant ever stop the committed criminal, this does add the level of complexity that may dissuade them.
