Secure towing starts with the right hitch lock

The CURT 23021 hitch lock adds a stout, deadbolt style shield to your trailer setup. Crafted for durability, it uses a 5/8 inch diameter pin that fits most 2 inch, 2-1/2 inch, or 3 inch receivers. The solid lock mechanism and heavy duty finish make it feel substantial in hand, inviting you to lock up when you park or tow.

Built to perform in real world use

When you leave your boat at the marina or your ATV at a campground, you want to feel confident that the ball mount stays put. This lock’s high strength steel body resists prying, while the 1/4 turn operation lets you secure or release quickly. The weather sealed dust cap protects the internals from rain, mud, and road grime, reducing maintenance and corrosion risk.

  • Easy operation: Deadbolt style lock with a simple 1/4 turn action for fast locking.
  • Weather ready: Watertight dust cap shields components from moisture and debris.
  • Versatile fit: Works with most 2 inch, 2-1/2 inch, and 3 inch hitch receivers thanks to the 5/8 inch pin.
  • Dual-keys: Includes two keys so you have a spare for emergencies or a trusted helper.

Smart security for multiple tow setups

Pair the CURT hitch lock with a coupler lock for a dual-layer approach that covers both vehicle side and trailer side security. Whether you’re towing a boat, an ATV, a camper, or other gear, this lock adds a discreet, robust layer of protection without complicating your routine.

Quality you can rely on

CURT uses a corrosion resistant chrome plating to shield the pin and internal parts, helping maintain smooth operation under outdoor conditions. The included watertight dust cap plus the reinforced locking mechanism provide a durable solution that’s easy to carry on trips and store when not in use.
