Fastway Fortress Universal Coupler Lock, (86-00-5015)

The Fastway Universal Coupler Lock keeps your trailer secure. It is the toughest coupler lock available, made from the highest corrosion resistant material and fits virtually every coupler style. In fact, after years of testing, we haven’t found a coupler it doesn’t fit. The lock has a hinged cover, protecting it from dirt, debris, rust, water, and ice. With its thick housing, incredible strength, and a lock that’s almost impossible to pick, you can be confident your trailer is safe.

  • Universal Compatibility: Fits virtually all 1-7/8”, 2”, and 2-5/16” tongue type trailer couplers to prevent your trailer from being stolen.
  • Two barrel-style keys included. This style of locks are harder to pick and much safer than others.
  • Anti-drill lock design.
  • Limited Lifetime Warranty
  • Unique shackle shape designed to prevent the lock from being pried off your trailer.

    I couldn’t quite get this to fit properly on the receiver of my Little Guy Max trailer, so I sent it back. I then watched a video with a sawzall ripping through a similar model, which kind of turned me off – it also seems to be rebranded under different names. Honestly, no thanks – even if it’s just for deterring thieves visually.

    I finally picked up a lock from Proven Industries. It’s a good fit and it definitely looks like it would deter any unwanted attention. It’s a bit finnicky and costs more, yep. Also, word of advice: don’t drop it on your foot. Man, that hurt.

    It doesn’t cover the whole hitch and can be split up.

    This lock seems to be very well made and fits …

    We use this for our boat trailer along with a tongue and wheel lock, so I’m not too stressed about it being our only protection. It’s super heavy and fits perfectly on our trailer. Plus, no one has messed around with it so far.
