3 Keyed Alike Universal Trailer Coupler Locks 379KA-3, Master Lock

#ad
Master Lock #ad - Rekeyable cylinder for keyed alike convenience with an advanced locking mechanism that resists picking and prying. The universal trailer coupler lock fits 1-7/8in 48mm, 2in 51mm and most 2-5/16in 59mm couplers by Reese, Dutton, Atwood, Lainson, Shelby, Hammerblow, Valley, Fulton, Putnam, and UFP.

This is a set of 3 keyed alike trailer coupler/tongue locks and is ideal when needing multiple locks that utilize ONLY one key. Few materials provide the strength and toughness of zinc alloys. Zinc alloys offer high strengths to 60, 000 psi and superior elongation for strong designs and formability for bending, plastics, crimping and riveting operations. These locks protects unattended trailers and guards against tow-away theft.

Impact resistance is significantly higher than cast aluminium alloys, and grey cast iron. And is simple to install and remove. 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. It also rotates less rigidity making it harder to break with sledge hammer force. The same key opens all three locks. In stock with a delivery time of 1 to 5 days.
