The package pairs a long coupler latch lock with swivel head receiver locks so the trailer is protected both when attached to the tow vehicle and when parked separately. The single biggest reason to buy is the combination of hardened steel construction and a keyed cylinder that prevents the coupler latch from moving, stopping removal or insertion of the ball.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoupler protection:\u003c\/strong\u003e The latch lock prevents the coupler latch from moving, which stops the coupler from being removed from the ball or from accepting a ball.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual receiver sizes:\u003c\/strong\u003e Includes 1\/2 in and 5\/8 in swivel head receiver locks, providing security for Class I through IV hitch receivers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable construction:\u003c\/strong\u003e The coupler lock is hardened steel and the components are chrome plated for improved wear and corrosion resistance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecure keying:\u003c\/strong\u003e A precision 4 pin tumbler mechanism resists picking and uses a common K1 key blank for replacements or keyed-alike setups.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeather resistance:\u003c\/strong\u003e The receiver lock has a Weather Tough seal and a snap-on cap to keep dirt and moisture out of the keyway.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEasy locking:\u003c\/strong\u003e The receiver lock features a push-to-lock mechanism and a 360 degree rotating head so the keyway can face forward for convenience.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThis bundle is best for trailer owners who tow boats, utility trailers or small campers and want a visible, mechanical deterrent against theft while towing or parked.
