CZC AUTO Hitch Receiver Pin Lock — Dual 1/2" & 5/8" Pins, Chrome-Plated Carbon Steel, Push-to-Lock

CZC AUTO Hitch Receiver Pin Lock is a dual-pin, key-protected hitch lock engineered to secure 1-1/4", 2" and 2-1/2" trailer receivers using both 1/2" and 5/8" pins.

This heavy-duty hitch lock combines two common pin diameters in one compact unit so you don’t need separate locks for different receiver sizes. It uses chrome-plated carbon steel for strength, a push-to-lock mechanism for fast operation, and a removable keyed head with dust cap to reduce corrosion. The lock works with bike racks, cargo trays, hitch balls and tow ropes across Class I–IV receivers.

How does the dual-pin design simplify towing setup?

The dual-pin configuration covers the most commonly used hitch pin diameters—1/2" and 5/8"—so one lock fits multiple receiver types. You can switch pins depending on whether you have a 1-1/4", 2" or 2-1/2" receiver without buying additional locks.

• 1/2" pin: 3.0" effective length for smaller Class I/II receivers
• 5/8" pin: 3.5" effective length for larger Class III/IV receivers
• Replaces separate locks for bike racks, cargo trays, and hitch balls

How easy is it to lock and unlock the CZC AUTO hitch pin?

Locking is a quick, tool-free push-to-lock action—listen for a click and pull the head to confirm the lock engaged. To remove the pin, insert the flat key and turn a quarter of a rotation; the same key style is simple to copy if you need a spare.

• Push-to-lock: audible click confirms engagement
• 1/4-turn keyed release for secure unlocking

What materials and features protect against wear and corrosion?

The lock is built from chrome-plated carbon steel for toughness and resistance to bending. A rotating head makes handling easier when installing or removing the pin, and a dust cap covers the keyway to reduce ingress of moisture and grit.

• Chrome-plated carbon steel body for strength
• 360° rotating head for easier alignment and access
• Protective cap over keyhole to limit rust and debris
