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

Fits well, easy to install, a little heavy

Very easy to use lock. Adds a high level of security.

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.

This was a great lock in the beginning. However, I did not use my fifth wheel during COVID. The Amplock device remained locked in a secure yard on my fifth wheel. Recently, I took the lock off and I noticed that the locking barrel that slips over the fifth wheel tongue was a bit hard to removed. I used a light lubricant on it. Later, it became more difficult to remove. After the last time I removed it, I was afraid to put it on again for fear that I would not be able to remove it. The locking barrel is keyed and it does not work properly. What good is a lock if even you cannot remove it with the key in hand? DONT BUY THIS! It is a good lock but has a cheap locking mechanism.

It worked great. Installed on 35ft 5th wheel. Montana

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

Very nice heavy duty product. Easy to lock and unlock.

Simple to use

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.

Well designed. Gives you confidence that our rv is safe.
