FixOasis Universal Trailer Coupler Lock for 2-5/16" & 2" Balls — Full-Wrap Forged Steel, Weather-Resistant

This adjustable trailer coupler lock from FixOasis combines rugged construction with quick-fit convenience to protect your trailer when parked or stored. Built with hardened steel and finished with a weather-resistant coating, the lock is engineered to resist cutting, prying and drilling attempts while fitting common coupler sizes. Choose from steel puck locks for maximum cutting resistance or aluminum-alloy puck locks in red or black for high-visibility deterrence.

How does the FixOasis Universal Trailer Lock stop thieves?

The lock uses a full-wrap design that encases the coupler and trailer tongue, eliminating easy pry points and covering the latch area. Its forged components and anti-drill construction make brute-force attacks more difficult, and the visible puck lock options act as a psychological deterrent.

• Full-wrap steel frame prevents access to the coupler latch and chain attachment points
• Hardened steel construction resists cutting and sawing attempts
• Puck lock options include anti-drill steel or bright aluminum-alloy for visibility

Will this lock fit my trailer coupler?

The FixOasis Universal Trailer Lock is adjustable to fit standard 2-5/16" and 2" ball couplers as well as common Bulldog-style couplers. It is not suitable for couplers that have uncommon top plates, square features, or special structural variations, so measure your coupler before ordering.

• Compatible with 2-5/16" and 2" round ball couplers and many Bulldog couplers
• Not compatible with couplers that include square tops or nonstandard structures
• Adjustable slider lets you tighten the fit to the trailer tongue for a secure seal

How durable is the lock in bad weather and heavy use?

FixOasis treated the lock with a durable powder coating that helps resist rust and corrosion from sun, rain, and snow. Key components are forged or alloyed to sustain repeated installation and removal, and the finish is designed for long-term outdoor exposure.

• Powder-coated surface for corrosion resistance and long outdoor life
• Forged heavy-duty steel frame withstands repeated mechanical stress
• Designed to remain functional through seasons with minimal maintenance

How quickly can I install or remove the trailer coupler lock?

The lock features an exclusive quick-release core and an adjustable slider, allowing most users to mount or remove it in under 30 seconds without specialized tools. The puck lock design also simplifies locking and unlocking while keeping the mechanism compact.

• Quick-install design typically assembled or removed in 30 seconds
• Adjustable slider ensures a snug, rattle-free fit on the tongue
• Puck lock system provides a low-profile, tamper-resilient closure
