Will this lock fit my 2" receiver hitch?

The TOPSHINE hitch pin lock is sized to fit receivers designed for a 5/8" diameter pin. It provides a usable shank length of approximately 2-4/5", which accommodates the majority of Class III and IV 2" receivers.

• Pin diameter: 5/8" (verify your receiver pin hole is 5/8").
• Usable length: roughly 2-4/5" for standard single-walled receivers.
• Not compatible with double-walled receivers—measure inside depth before purchase.

How secure and durable is the TOPSHINE hitch pin lock?

This lock uses high-strength steel for the pin and a powder-coated body to resist impact and corrosion. A rubber key cap protects the cylinder from water and dirt, while the keyed-alike design reduces key clutter without sacrificing convenience.

• High-strength steel construction to resist bending and forced removal.
• Powder coat finish for improved corrosion resistance outdoors.
• Rubber dust cap protects the keyway from moisture and debris.

How easy is it to use day-to-day?

Operation is straightforward: insert the lock, give the cylinder a 1/4-turn to engage, then tug to confirm it’s secured. The keyed-alike package includes four identical keys, so you can keep spares or share with a co-driver without needing key matching later.

• One-quarter turn activation for quick locking/unlocking.
• Pull-check recommended after locking to verify engagement.
• Four identical keys included for convenience and emergency access.

How does it stand up to weather and long-term use?

The TOPSHINE design keeps the lock functioning through exposure to rain and road grime. The rubber cap minimizes moisture entry into the cylinder, and the exterior coating reduces surface rust, extending service life when used as intended.

• Weather-resistant rubber cap keeps the keyhole cleaner longer.
• Powder-coated body reduces corrosion in outdoor conditions.
• Sturdy mechanical components for repeated daily use.

Who is this for: The TOPSHINE 5/8" Black Hitch Pin Lock is intended for trailer owners, RV users, and drivers of vehicles that accept a standard 2" receiver who want a simple, durable anti-theft solution. It's well-suited to anyone who needs quick, repeatable locking with multiple keys—campers, contractors, fleet vehicles, and families sharing a tow setup. Before purchasing, confirm your receiver accepts a 5/8" pin and is not double-walled to ensure proper compatibility.
