About this item

  • [Keep Your 5th Wheel Secure] : King pin lock can prevent thieves from connecting your fifth wheel kingpin and avoid unauthorized movement. The durable construction, eye-catching yellow lock and tag serve as a warning and deterrent against theft to keep your 5th wheel secure.
  • [Dimension]: The dimension of the trailer king pin lock is 83 mm in height, with an internal diameter of 74mm, a universal fit for 50 mm diameter trailer pins. Thus, the lock can be widely applied in semi trailers, 5th wheels, trucks, boats, containers and many other scenarios.
  • [High Quality Material]: Trailer king pin is made of heavy duty steel copper, processed with welding construction. The surface adopts electrostatic treatment, featuring the body with weather resistance and anti-rust, making it sturdy enough and hard to break even by experienced thieves. Therefore effectively increase the safety factor and reduce the probability of theft when installed onto trailer.
  • [Warning Tag]: The main tone of bright yellow designed as a sign of strong visible warning. The chain with fluorescent warning tag hanging down passes on message to someone to try and steal : Caution! King pin lock installed! If a would-be thief sees the lock, they'll likely move on to an easier target.
  • [Easy to Use]: The trailer hitch lock is rather easy to use. You just need to engage the lock onto the trailer hitch, then insert the key into lock cylinder and rotate 180 degrees, the king pin lock firmly installed. (Attention: Every lock has its own keys. Different locks don't share the keys.)

This little contraption works wonderfully! It's amazing how such a simple device can do the job you want done without costing a fortune and visibly obnoxious! Very well made, works perfectly, not a glaring clue to evil perpetrators that you your camper has gold bullion under the bed, LOL. Do we feel safer now? YES!

I got this to secure an RV, mostly to encourage the owner to pay for the rental space. It is highly visible and is easy to use install.

Good fit and keys are nice. Plastic chain was broken for the tag. A metal chain would be better.

Sturdy and the lock appears hard to pick based on my little knowledge of locks. It does have a good warning tag though the chain is plastic.

I purchased two of these pin locks and it works great. The keys are a special kind of key and nice and bright. I strongly recommended.

Keeps the king pin secure. Comes with two keys. The "chain" is plastic. So might replace it.
