VEVOR Trailer Coupler Lock 2-5/16 in

This heavy-duty lock secures a 2-5/16 inch flanged air flow coupler on a trailer tongue. It is built from carbon steel with a protective surface coating and weighs 10.36 lbs. The package includes the lock body, a matching bottom connector and three keys.

Upgrades from basic pin or padlock security

A simple hitch pin or standard padlock can be cut or bypassed quickly. This lock encloses the coupler mechanism with a 0.24 in wall thickness and an internal diameter of 5.04 in, making forced removal far more difficult. The jump is worth it when the trailer carries high-value cargo or sits unattended for long periods.

Check coupler style and dimensions before ordering

The lock fits only flanged air flow couplers sized at 2-5/16 in or 58.6 mm. Verify that your coupler matches this exact type and size; other styles such as straight-tube or A-frame couplers will not accept the bottom connector. Also confirm the 5.59 x 6.89 in external footprint clears surrounding jack hardware or frame brackets.

Questions about this item

Will the 5.59 by 6.89 inch body and 0.24 inch wall thickness clear my 2-5/16 inch flanged air flow coupler?

The lock body measures 5.59 x 6.89 inches with a 0.24 inch wall, giving an internal diameter of 5.04 inches and depth of 4.92 inches that fully encloses a 2-5/16 inch flanged air flow coupler.

Do I remove the supplied bottom connector before sliding the lock over the coupler, or does it stay in place during installation?

The 2-5/16 inch bottom connector stays attached; slide the lock over the coupler, seat the connector into the ball socket, then turn the key to engage the internal locking bar.

How often should I lubricate the lock cylinder and inspect the carbon steel body for coating wear?

Apply a light PTFE lubricant to the cylinder every six months and check the surface coating for scratches or rust after each heavy tow season.
