8 Keyed Alike Universal Trailer Coupler Locks 379KA-8, Master Lock

#ad
Master Lock #ad - Limited Lifetime warranty. These locks protects unattended trailers and guards against tow-away theft. Zinc alloys offer high strengths to 60, plastics, 000 psi and superior elongation for strong designs and formability for bending, crimping and riveting operations.

Few materials provide the strength and toughness of zinc alloys. 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. This is a set of 8 keyed alike trailer coupler/tongue locks and is ideal when needing multiple locks that utilize ONLY one key. Each lock weighs 2. 4 lbs. And is simple to install and remove. The same key opens all eight locks.

Rekeyable cylinder for keyed alike convenience with an advanced locking mechanism that resists picking and prying. Each lock comes with two keys, therefore you will receive a total of sixteen keys with the purchase of this 8 pack. 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. Made with reinforced zinc die-cast resists rust and corrosion.
