AMPLock U-LPCVR 5th Wheel Lock | Heavy Duty King Pin Lock for Travel Trailer | Conical Lock Made of Ductile Cast Iron | Prevent Traction with Chains, Rust Resistant | Made in Canada

Simple to use

This lock is a beast. It is easy to use and high quality of fabrication really stands out.

Solid design with great powder coat. Well worth the money.

One of the best king pin locks that I have used. Very well constructed and extremely heavy duty.

Lock is very heavy duty and well made. It is easy to install onto the fifth wheel hitch and gives peace of mind that the trailer is secure.

This lock is certainly the sturdiest lock in the RV park from those I have seen and used on other 5th Wheelers. Some reviews have said it was heavy and that is precisely why I purchased this lock over the competitors. I wanted something heavy and sturdy and this is it. Just from the shear size of this lock, I bet it would be easier for the potential thief to unbolt the King Pin Hitch and simply put on a new hitch rather than to try to cut the lock off. Another reviewer said, the lock will keep the honest people honest. I fully agree with that statement. This lock wont be easily defeated.

Didn’t exactly fit for our 5 wheeler... had to cut the back area to fit it in

locking mechanism feels solid. im not a lock expert, but the keys are unusually designed, so it looks like they would be difficult to copy, and the lock difficult to pick. not cheap, but worth a peace of mind, especially if leaving your RV unattended. Extra points for made in Canada, not China.

Easy to attach. Seems like it would be very hard to get off.

Solid, light weight, gives me a piece of mind when boondocking.
