Product was easy to put around the tire of our trailer. Product appears sturdy. Appreciate the two keys were included!



by:

wheel chock and lock works great. also a visible deterent. this is my 3rd one. first 2 are still being used after years of exposure to the elements. WI winters can be very harsh on anything left outdoors.



by:

As always another quality solid product. Sure is nice never being disappointed with anything I've gotten for my trailer build. Fast shipping every time too!



by:

We use them for our Speed Trailers on the side of the roads



by:

We have the Trimax Chock/Lock several times and we still have our trailer. j



by:

Just big enough for my 15" tires. Width is plenty, but could use slightly more depth towards center of wheel. Feels good and solid on the wheel and the chock works well.



by:

Product was exactly what I was looking for to secure my trailer. Very fast shipping which surprised me as it was around Christmas time.



by:

I received my wheel lock today and was under the impression that I would receive three keys. That was stated in the features of the product. I was informed by the etrailer rep that she was sorry but the pictures and the videos stated two keys. Quite honestly, I did not view the videos and did not see that the pictures only had two keys as I had read that there was three keys included. I also, learned I would need to go to manufacturer for additional keys. She did say that she had contacted a team member and the add would be changed on the website. She asked me if I wanted a return form. It is not a deal breaker that only two keys are included but, again you don't receive what you think you are purchasing. The wheel lock seems to be well made and I will update as soon as I install it. G



by:

Looks like it will work well. One more visual deterrent, hoping it will make the dirt bags just pass me by and move onto the next unprotected trailer.



by:

Really good quality, thanks etrailer!!



by:

Easy install and good quality



by:

Lock works great! Customer service helped us split order for delivery due to other item delayed from manufacturer. They were a great help.



by:

Deliver, customer service and ordering process was done very smoothly.



by:

Easy to deploy and give security and peace of mind when leaving trailer at campsite. I use them in my driveway to keep the trailer from rolling. works great!



by:

Awesome! Great service and quick deliv ery!



by:

Easy to use, nice peace of mind knowing the camper is not going anywhere and is a great chock. The groove side of the chock settles down onto all surfaces beautifully.



by:

very nice unit, great quality!



by:

Perfect fit for my vehicle. Heavy weight, sturdy construction.



by:

Using on a 4.8 x12 wheel. A little loose but will work. Seems a little tough to lock but maybe practice will help. Should act as a good deterrent.



by:

Easy to use—the hardest thing was getting it out of the packaging. Seems solid.



by:

This wheel lock fits perfectly on our KarKaddy. It gives us a sense of security when we have to leave it in an unattended area. Shipping was fast. It was also packaged well.
Thanks



by:

WELL, IF YOU HAVENT PURCHASED THESE FOR YOUR TRAILER OR MOTORCYCLE YET THEN YOU NEVER READ MY LAST REVIEW AND NEED TO ORDER THESE NOW! STILL L?? K GREAT AND EVEN LAW ENFORCEMENT WAS IMPRESSED ??



by:

I have used this brand of trailer wheel lock before and knew it was exactly what I needed to secure my Uhaul trailer overnight when relocating. When hauling any enclosed trailer, and especially a Uhaul, you are pulling a traveling “steal me” sign to thieves. This gave me piece of mind knowing it would be a deterrent to make thieves move on to an easier target. Easy to use. Well worth the money.



by:

Works really well as a deterrent for people that want to steal your stuff. I used one on my enclosed trailer and currently put one on my wheeler that I’m trying to sell. Not sure if all of them are keyed the same but the two I bought were.
