Master Lock, 4 Keyed Alike Universal Trailer Coupler Locks 379KA-4

#ad
Master Lock #ad - Limited Lifetime warranty. Made with reinforced zinc die-cast resists rust and corrosion. Each lock weighs 2. 4 lbs. And is simple to install and remove. It also rotates less rigidity making it harder to break with sledge hammer force. Impact resistance is significantly higher than cast aluminium alloys, and grey cast iron.

Each lock comes with two keys, therefore you will receive a total of eight keys with the purchase of this 4 pack. This simple design is difficult to defeat because when it's locked on the trailer the lock rests on top of the coupler see image thus thwarting blunt force from downward hammer strikes. These locks protects unattended trailers and guards against tow-away theft. Zinc alloys offer high strengths to 60, 000 psi and superior elongation for strong designs and formability for bending, plastics, crimping and riveting operations.

The universal trailer coupler lock fits 1-7/8in 48mm, lainson, hammerblow, Valley, Shelby, Putnam, Fulton, 2in 51mm and most 2-5/16in 59mm couplers by Reese, Dutton, Atwood, and UFP. The same key opens all four locks. Few materials provide the strength and toughness of zinc alloys. This is a set of 4 keyed alike trailer coupler/tongue locks and is ideal when needing multiple locks that utilize ONLY one key. In stock with a delivery time of 1 to 5 days.
