DeadBolt Trailer Hitch Lock for Class V 2.5" & 3" Receivers — 1/4-Turn Quick-Release, Weatherproof

DeadBolt’s Trailer Hitch Lock is a heavy-duty Class V locking system for 2.5" and 3" hitches that secures your trailer with a fast 1/4-turn mechanism and rugged, weatherproof construction.

Whether you tow a heavy trailer, RV, or commercial equipment, this lock is engineered to stop unauthorized hitching and protect your investment. Designed and manufactured in Michigan, DeadBolt combines decades of towing know-how with cold-forged steel components and a sealed lock housing to withstand road use and harsh weather. The compact key design, reversible key blade, and non-slip grip make it easy to operate from a hitch receiver while a powder-coated finish helps resist corrosion during long-term exposure.

How does this lock fit different Class V hitch receivers?

The DeadBolt fits standard Class V receivers and accommodates both 2.5" and 3" hitch configurations, giving broad compatibility across heavy-duty trailers and tow vehicles. Its pin diameter and locking profile are specifically sized for the heavier loads Class V systems carry.

• Compatible with Class V (2-1/2" x 2-1/2") receiver openings and common 3" adapters.
• Cold-forged carbon steel pin sized for heavy towing forces.
• Works with typical trailer couplers and hitch adapters used in commercial towing.

How quick and simple is the 1/4-turn locking mechanism?

The quarter-turn system locks or unlocks with minimal rotation of the key, letting you secure or remove the lock quickly even in tight or awkward positions. The key is flat and reversible, so you won’t fumble trying to orient it before turning.

• Fast 1/4-turn action for rapid installation and removal.
• Reversible automotive-style key inserts for intuitive use.
• Weatherproof key cap included to protect the cylinder from dirt and moisture.

Will it stand up to harsh weather and frequent use?
