The Best Security
for your Trailer or RV

Prevent theft of semi-trailers and valuable cargo with the new King Pin lock from Master Lock. The lock fastens to the king pin of an unattended trailer and blocks attempts to hook to an unauthorized tractor.

The Master Lock King Pin Lock has many advantages that increase security
and convenience for your fleet:

• Constructed of solid, cast aluminum alloy, the housing is engineered to withstand physical attacks, yet weighs only 6.5 Ibs (3 kg) making it easy to carry.
• The lock, protected by the housing, is designed to resist common attempts to defeat standard locks.
• No accessible shackle to cut.
• Hardened steel bottom plate resists drill attacks and any attempts to pull the cylinder from the lock.
• The durable bright red powdercoat finish and the red flag is visible to the driver from a distance.
• Chisel attempts are fruitless with the countersunk rivets holding fast.
• Also available keyed alike and master keyed for your convenience.
• The handle makes it easy to carry and easy to keep your hands clean.

CONSIDER THE MASTER LOCK ADVANTAGES:

• Secures the king pin of semi-trailers, RVs, and other fifth wheel trailers

Master Lock makes complete trailer security
even more convenient with many keying options:
