Trimax TCL75 Deluxe Universal Wheel Chock Lock-Yellow/Red

Great quality and value for price. Easy to use and durable. Works well.

This seems like a great product. I use the word "seems", because there really is no way to tell unless someone attempts to take your vehicle/trailer/RV. That being said, the quality is a solid build. It's constructed of heavy steel and is powder coated with rubber ends to protect your rim from scratches. It's relatively heavy due to the build and will stay in place once set. There is a convenient locking cover to prevent debris from entering the key slots, which is good considering it is meant to be on the ground.As for a chock, it works, but since you can't make a solid connection to the wheel or wheel rim, there will be play. It's my opinion, the chocking feature is only to prevent it from being stolen. The only way to ensure it is used as a chock is to move the vehicle/trailer forward/backward to ensure the wheel/rim is resting on the lock itself. This may potentially make it difficult to remove until you move the vehicle back. I bring this up, because I look at this as a "lock" first and potential chock second. The lock/chock works to prevent the vehicle from being moved. This means, it is prudent to ensure your your trailer is properly secured and chocked by other means. This lock/chock should be used as a supplement and not your primary chocking device. If used on a motorized vehicle like your car/truck, then it is not that big of deal since it has parking brakes, transmission park, etc. I'm specifically referring to trailers that do not have their own parking brake systems like travel trailers.As stated, I use this to supplement an existing system. I use traditional chocks on my wheels as well as trailer hitch lock on my trailer as other means to secure my trailer. This is not (at least I don't think) to be used as a one-stop-shop device that can do both on its own. Overall, I would highly recommend this product due to its build and extra layer of protection. If you're an RV'er, this may not be necessary when you're actually on the road as most RV'ers look out for each other. That being said, when you store your RV, this is something you may want to consider to supplement your existing system.

Purchased August 2024. Have used this extensively on a VERY expensive enclosed motorcycle trailer with no issues. Understanding that this device is a deterrent only and won't stop a determined criminal, incorporated with other deterrents on the trailer, it will "slow them down". I place the locking stem mechanism to the INSIDE of the wheel, making it slightly more difficult to access.

Robust, high quality wheel locks.

This is a good, substantial lock. Easy to use and a good theft deterrent. I bought the TCL65 earlier and now the TCL75. This photo on the product page notes that the chock locks come with 3 keys. The detail on that page says the lock comes with 2 keys. It only came with 2 keys unfortunately. I believe in the past the locks came with 3 keys. That wouldn't be such an issue except the keys are "proprietary" as Trimax says and to order a replacement key is nearly $20 with shipping charges. That's pretty expensive for just a key, even given the need for shipping and handling.That's disappointing.
