Master Lock 387NKA-2 Keyed Alike King Pin Locks with BumpStop Technology - Secure Toy Hauler & Trailer Locks for RV, 5th Wheel, and Travel Trailers - Heavy Duty Anti-Theft Protection for Outdoor Adventures

This durable high security keyed alike king pin lock protects your trailers and their cargo. This lock includes two keys. The reality is that trailer theft is quite prevalent throughout the United States and around the world. There are very few secured parking areas available to truck operators, and dropped trailers with no locking device are vulnerable to cargo thieves. Many king pin locks are ineffective in preventing a full trailer/container theft. For an effective theft deterrent look to Master Lock, the most recognizable and trusted locking company in the industry today. . LOCK BUMPING, a surprisingly simple method of breaking in through locked doors and padlocks - is undoubtedly the newest emerging threat to personal property security. And virtually all locks in use today are particularly vulnerable to bumping. Until now. BumpStopTM Advanced Cylinder Technology employs an innovative, patent pending design which utilizes a unique reverse rake tapered driver pin, high performance springs and tightly machined cylinder chambers. During a bump attempt, this design prevents the transfer of force from the bump key to the pins and therefore blocks rotation of the cylinder so that the lock remains locked.

Two locks keyed alike and 4 keys. This lock secures the king pin of semi-trailers, RV's, and other fifth wheel trailers. Solid, cast aluminum alloy withstands physical attacks.
