BOLT Locks launched a new Fifth Wheel King Pin Locking System, expanding its line of heavy-duty, weather resistant “Breakthrough One Key Lock Technology” offerings.
The BOLT Fifth Wheel King Pin Locking System works in conjunction with BOLT’s 5/8” Receiver Lock, which is sold separately, to prevent fifth wheel trailer theft.
BOLT’s King Pin Locking System features a U-shaped black powder coated hardened steel collar that wraps around the Fifth Wheel King Pin and attaches to a BOLT 5/8” Receiver Lock to securely hold the fifth wheel in place in the bed of the pickup. Together, the system acts as a visible theft deterrent, allowing the trailer to be secured with the owner’s truck key. The new BOLT King Pin Locking System is ideal for protecting camping trailers, construction trailers, and horse trailers.
BOLT’s 5/8” Receiver Lock is a stainless steel pin featuring a double ball bearing locking mechanism with a weather-resistant lock shutter to keep out dirt and moisture. Once the vehicle ignition key is inserted into the lock cylinder, spring-loaded plate tumblers move up and down until they are matched exactly to that key. The first time the key is rotated, the cylinder is uniquely coded to that key.
BOLT Locks’ growing line of products includes cable locks, padlocks, receiver locks, coupler pin locks, toolbox latch retrofit kits, and Jeep J-mount, spare tire and hood locks. BOLT Locks are available for Ford, GM, Chrysler, Nissan, Toyota and Jeep vehicles.
