• Critical Function: The hitch receiver lock features a high-strength structure and reinforced core, ensuring the connecting pin remains securely in place during towing. Besides, the high-security lock core blocks unauthorized removal or disassembly of the trailer, bicycle rack, or other accessories
• Thoughtful Design: The receiver lock comes with a rubber keyhole cover that seals out dust, sand, and water to avoid internal blockage. The provided O-rings create an elastic seal under pressure, increasing friction and minimizing accidental pin movement from road bumps
• Reliable Quality: Made of sturdy carbon steel, the trailer receiver lock can resist impact without deforming or breaking easily. The zinc alloy core has excellent corrosion resistance, ensuring smooth operation for a long time. The rubber cap is resistant to tearing and weather, providing reliable performance
• Convenient to Use: First, push the pin into the receiver and open the rubber cap. Then, insert and rotate a key counterclockwise to fix the lock. Simply insert the key and turn it clockwise when unlocking is needed. The cap can be quickly flipped open without having to remove it
• Broad Application: The hitch receiver pin lock features a 5/8" diameter pin and a 3-1/2" usable length, which makes it fit Class III and IV hitches with 2" and 2-1/2" receivers. It is suitable for most vehicles, such as trailers, trucks, SUVs, RVs, bike racks, boat haulers, etc., and is ideal for your towing tasks
